Chapter 1: A Quest Begins

 It is September 3, 1947, in the North Atlantic at Latitude 48° 12' North, Longitude 35° 15' West.  The submarine, with thirteen men and a girl aboard, has sailed from England to try to find the sunken treasure ships.  It settles to the bottom at 1,480 fathoms (8,880 feet), and,

     ... in silence the little group stood contemplating the weird, unearthly vista upon which no mortal had ever gazed before.
  And it well might have been the grotesque landscape of another planet.  A black, somber planet.
  This was a cold world in which no ray of sunlight had penetrated for two billion years.  (p.11)

 The situation for our intrepid explorers is not an auspicious one, because of course, having thirteen men aboard the ship would be jinx enough, but they've also got a girl along, traditionally bad luck aboard a seagoing vessel.  Dirk thinks, "it was a mistake to bring her along.  She'd cause trouble yet – a bunch of men and a girl, wait and see!"  (p.12)  It's not long before Dirk's thoughts are proven prescient, as the sub is pulled into the irresistible current of a vortex:

  With grinning Death as a chaperon, Von Benson held Ellen in a grip of steel, and the last thing she remembered were his lips approaching hers while her own arms, in spite of her will, stole slowly about his neck.  Then the world was split by the sound and shock of a terrific rending crash against the sub.  (p.21)

Chapter 2: Sinking of the Black Falcon

Flashback:  In 1765, Captain Roger Stuart of Plymouth, England, was commissioned to transport to America a large shipment of gold coins and a quantity of gems and jewels (with an estimated 1947 value of about three million dollars).  His wife, Barbara, accompanied him on the voyage as they were planning to relocate to the colonies.  Their young daughter was left temporarily with her grandmother in Plymouth.  The daughter presented her mother with a little ivory miniature inscribed:  "To my mother, Barbara Stuart, from her loving Jane."  (p.23)  She also made her father promise to write to her in mid-ocean, seal the letter in a bottle, and then throw the bottle overboard.  This letter included the coordinates of the ships at the time, and also mentioned sighting a spiral that was presumably the cause of the vessels' wreckage.  This letter will find its way to the daughter, Jane, when she's a grandmother, and would many years later be discovered by Ellen, prompting her fiancé to design and build the Ellen Stuart and attempt the salvage operation.

First Footnote:  An explanation as to how this innovative diesel-engine submarine is actually an atomic sub!

  While on a research project to synthesize petroleum, Phillip Montague discovered that diesel oil when subjected to electron bombardment would break down into its basic constituents, liberating vast amounts of heat and oxygen in the process.
  The heat produced steam, which powered the giant twin turbine motors.  The oxygen sustained life and provided floatation.  ...
  Splitting atoms at the time was amazing enough.  However, in later experiments, Montague was able to reverse the fission cycle by a system of reconstitution chambers that demanded only large quantities of cooling sea water to reform petroleum atoms into the original crude, inexpensive diesel fuel."  (p.33)

He also writes that the enormous steam pressure generated is regulated and directed between the inner and outer hulls, to counteract the enormous pressure found at great ocean depths.  But no mention is made as to why the enormous steam pressure doesn't make the inner hull implode.  It's also the only footnote signed (with the initials "J.R.B." – possibly a typo for "J.C.B." but more likely the initials of JCB's wife and long-time assistant in his art and writing projects, Jane Ralston Burroughs).

Chapter 3:  Death Strikes Twice

As the twisting submarine was pulled ever deeper into the black maelstrom, Von Benson found himself confronted by both the probability of death and the actuality of a beautiful woman in his arms.
The man's reaction was a logical one for him:  he chose to take the girl even as Death was taking them all!
However, his lips had no sooner touched hers than the crash occurred, and he looked up to see a geyser of steaming water shoot through the galley hatch into the passageway.  (p.35)

Von closes the hatch and sweeps the unconscious Ellen into his arms.  As Von carries her to her cabin, he explains to the doctor in passing that she's only fainted.  The geyser of water shot Mr. Flobs and the little spaniel dog out of the galley in time, but the mute stowaway Bucky was caught inside and presumably drowned.

Dirk, Von, and Wicks go outside to check things out, and Ellen offers to take command in their absence, but our hero declines her offer.  "Dirk surveyed her a moment.  'You're a woman and you faint too easily,' he said.  'Ellis is in charge – get back to your man.' "  Ellen, who had actually been given fourth in command status, after Dirk, Von, and Phil, quite naturally resents this, but since Phil broke his arm in all the gyrations and the breach of the sub and is therefore under opiates at the moment, she now spends a lot of time nursing him.

Second Footnote:  (p.39)  A pretty nifty description of the aluminum alloy, segmented, deep-sea diving suit they use, with a double-door in the helmet to pass in food, two-way radio sets built in to the helmets, and mechanisms for air-recycling and waste disposal.  It's equipped with a short-handled ax worn at the side.

 Outside the sub, Dirk and Von have gotten a bit ahead of Wicks.  They come back to find him dead after fending off some unknown monster with his ax, the blade of which is still smeared with blood.  (p.43)  It will turn out that he died of a heart attack, as he had a weak heart, and they are left to wonder what manner of creature attacked him.  After they bring Wicks back aboard and the doctor does his autopsy, Dirk goes back outside to bury the body in the sand, instead of doing the usual "burial at sea."  (p.46)  They are now at 3,000 fathoms (18,000 feet), but the pressure gauge registers only the pressure found at thirty fathoms.  (p.51)  It will remain this way for the rest of the novel, which is convenient as it lets folks move about a lot more easily!

Chapter 4:  "Bucky's" Head Returns

The chapter title gives it away:  the mute stowaway Bucky's head is seen floating outside the submarine, alive and looking in at the portholes.  A fin is now where his neck was.  They wonder if it isn't some strange fish that just happens to look like Bucky.

Von now goes to the cabin where Ellen is caring for her fiancé and Von's good friend, Phillip.  Desperate as their circumstances seem in a disabled sub at the sub-bottom of the bottom of the sea, Von now clutches a yielding Ellen and tries to do her on the deck, right beside the bunk where Phillip lies unconscious, but a wave of revulsion, remorse, and shame sweeps over her.  She pushes him off, and he becomes like a giant, maddened beast; however, no one goes primordial battle yet.  Dr. Kingsley quietly interrupts them, and Von bides his time.  (p.53-54)

They are now at 3,500 fathoms and the tunnel through which the vortex has been pulling them levels out, ten hours after they were first caught in it.  They find the three sunken vessels they were seeking.  They guess that the ships sank straight downward, just so happening to end up at the same spot that their vortex tunnel landed them (which conveniently takes care of any questions the reader might have had as to why the ships are still intact, when the wooden brigs could not have withstood the vortex that has nearly wrecked the sub).

Chapter 5:  The Sunken Vessels

 This next bit is told from Dirk's point-of-view (as is most of the rest of the novel), with Dirk waking up at the sub's engines being started, thinking that Von is commandeering the sub.  Dirk rushes through the sub to find that Phillip – delirious and thinking they're all Nazis – is wielding a .32 automatic and using the last remaining fuel to gun the sub across a trench so they can get to the three ships.  Dirk and Von face Phil off, with Dirk dropping to the floor – a bullet whizzing over his head – and Dirk then knocking Phil cold.

 Dirk and Von suit up and go to the nearest ship, while Ellen – refused permission to accompany the fellas – suits up and goes out on her own to the farthest brig, the Black Falcon.  She finds the rather unique remains of her ancestors, Roger Stuart and his wife Barbara, to be just shells of their former selves.  Their corpses were apparently quickly covered by small sea creatures, whose tiny, calcified remains then completely coated the outsides of their hosts when they died.  Splits in the sides of these shells reveal the insides to be hollow, but the exteriors are so finely covered that the facial features are recognizable from paintings Ellen had seen of them.  Ellen also finds the miniature that her ancestor, Jane Stuart, presented to Barbara, on that day 182 years earlier.  (p.73)

Undeveloped Jogulars now make their first appearance.  They look like giant brains with a single eye right in their centers, and are able to exert a semi-paralyzing hypnotic influence telepathically.  One of them draws Ellen back into the cabin where she found the shell of Barbara Stuart.  Ellen faints.

Chapter 6:  "Like a Huge Brain!"

Dirk now gets to tell Ellen, "I told you that you faint too easily," (p.82) after he and Von bring Ellen back to the sub.  They find out the reason why Phil has been so badly off when he just suffered a broken arm:  he had also ruptured a kidney, that had now become badly infected.  The doctor had to perform immediate surgery; however, because their morphine supplies are depleted due to the storage area having been flooded when the sub's hull was breached, Phil may not survive.  Von viciously slaps Dr. Kingsley around, as a form of discipline, and to make him do better for Phil, until Dirk reminds Von that the Doc can't do better for anybody if Von kills him.  Now the big revelation!  It turns out that the reason the doctor has been rather twitchy of late is that he is a long-time morphine addict.  A true physician, however, the doctor has already volunteered the entirety of his personal supply of morphine for use by Phil.

Chapter 7:  Mysterious Lights

After some clever business where they find nothing but lumpy gunpowder in the treasure chests, but then find the gold and jewels after all, hidden under more gunpowder in the gunpowder kegs, Von and the crew celebrate by getting sloshed on rum.  Dirk, who refrains, thinks:  "The submarine was a powder keg, anyway, with men, gold, danger and a girl – that rum could just be the spark to set it all off."  (p.90)  While the rest of the crew are three sheets to the wind, Dirk looks out a porthole and sees mysterious lights on the wrecks of the ships.  These turn out to be from a raiding party of Jogulars, who carry away the bulk of the gold to their city – that is just across the valley and over a pass between two buttes – but a fair hike away from where their sub is now parked.

 This is where Willoughby reports that he has made radio contact with the S.S. Courageous and that two rescue vessels are now on their way from England!  Their dilemma:  they can be rescued, but what about all their gold that some mysterious creatures have carried off?

 To keep things moving, I'll skip ahead and interject here that Willoughby is a raving loony – because of his well-known whimpering fear, and because of the same mysterious parasitic infection that made Phil go bonkers.  (It is even likely that these are the same parasitic microorganisms that have turned Bucky's head into a seagoing creature, but this is never explicitly stated.)  Willoughby later reveals his delusional state to Dirk in Chapter 9 (p.107), right before he goes into a screaming mania and dies.

Note for Weapons/Technophiles:  (p.94)  The underwater rifles they use are insulated, automatic carbines, that "caused the crystallization of the salt in sea water into pellets that were ejected from the muzzles with the speed of bullets, by the energy given off by the crystallization process itself.  ...  It was similar in principle to the later well-known Aqualian rifle used by the hordes that over-ran the city of San Francisco."  (p.94)   It's later mentioned that the rifles use cylinders of ammonia gas.  (p.133)

[Unless you know something I don't, I'm guessing the reference to the "Aqualian rifle used by the hordes that over-ran the city of San Francisco" was thrown in to give greater reality to the story, much as later footnotes do that refer to reports now in the Smithsonian (p.110), and Dr. Kinglsey's journals being published (p.223).  On the other hand, maybe this reference is to another novel that JCB planned?]

Chapter 8:  Dr. Kingsley's Theory

Phil dies suddenly – but did he die of a non-fatal dose of saline solution that somehow got into his penicillin?  No, the autopsy shows that his "skull cavity ... at the time [the doctor] examined the contents, did not contain a human brain."  (p.100)  The doctor tells Dirk that he has seen a similar structure – of strangely interlocking cells with astounding capacities for expansion and contraction – in the puffer fish found off Madagascar.

Again, to keep the suspense and confusion in check, I'll simplify later explanations and insert them here:  the parasites that have infected Phil and Willoughby were gradually replacing every cell of their brains with a replicated cell, composed of its own soft, whitish-colored jelly/protoplasmic kind of material.  The microorganisms that make up this material form a collective being of replicated cells.  Eventually, they entirely consume the brain, and then the entire body, resulting in a copy of the original person in appearance and in memory.  They also grow gill-like slits in their necks and a single, functional eye in the middle of their foreheads (their replicated original eyes are sightless).  These parasites  infect and replace tissue in dead bodies in the same manner, with the addition of sometimes replacing their clothing with jelly/protoplasmic material, too.  In the case of Roger and Barbara Stuart – and a host of other bodies over the last two thousand years or so – their Jogular replicas had formed inside the shell created by the coating of dead crustaceans that had covered their corpses.  When the transformations were complete, they broke from their shells (thus the cracks in the sides of Roger's and Barbara's shells that Ellen had seen) and instinctively went to the crater at the bottom of the ocean where the Jogular city is found.  They cannot speak or hear, but communicate telepathically.  The undeveloped Jogulars that look like giant brains are the parasites that never found a host, but floated about and grew up on their own.  They are also telepathic, with an extra strong ability to control the minds of others.  (pp.158-163 goes into great detail about the exact process and nature of the microorganisms, with very scientific sounding footnotes)

Chapter 9:  Three Vanish

This is where Willoughby's lunacy is revealed and he dies.  This is also where the girl starts putting things together that Dirk realizes even he hadn't connected yet.  (p.110)  Von Benson and Hill choose to follow the tracks left by the Jogulars that snatched the gold, and they finally return to the sub after being gone for four days.  Hill dies after mumbling about a city of strange people, but Benson falls asleep and seems normal when he awakes.  Shortly thereafter, Dirk finds the officer on watch has been clobbered, two .45 automatics have been taken, three diving suits are missing, and all the remaining oxygen tanks sabotaged, except for the two that were inaccessible while being recharged.  Benson, Harry Grube, and Ellen are missing, and Dirk and the doctor go after them.  The love-story for the hero and the girl essentially starts here, with Dirk showing his growing feelings for Ellen by agonizing over the question as to whether she went willingly or not.  In this underwater jungle, Dirk leaves the doctor in his wake, and then Dirk is attacked by a huge wasp creature with fangs and a stinger.

Chapter 10:  A New World

 Dirk struggles to fight the enormous thing – in the first man vs. creature battle in the novel (and we're already on p.123!).  After a bit of a struggle, he manages to cut it in half at its wasp waist.

 The doctor, meanwhile, encounters an undeveloped Jogular, and despite its paralyzing hypnotic effect on him, is left with the impression that it was trying to communicate with him, primarily conveying the thought:

  "...that it was already part me – that I was part of it – and sometime, very soon, we would be merged into ONE."
  "Maybe it was a lady brain proposing to you," Dirk suggests.
  The tension left Dr. Kingsley, and he found himself chuckling.  "Good heavens!" he said.  "And at my age!"  (p.126)

 Now as the doctor remarks, it'd be "easy to believe we've been transported to another planet."  (p.128)  Accordingly, we get the speculation regarding the crater they've found being evidence of a "meteor that had struck the earth in the long-gone past before the ocean had buried the land."  (p.129)  Conveniently – so our heroes don't have to keep trudging around in their diving suits – the earth emits air through fissures at this point, at a slightly greater pressure than the water it displaces, forming a vast, habitable, air bubble that our people can penetrate.  (p.130)  Once inside, they doff and cache their suits and tanks, and start out to explore the rivers, forests, and dimly seen creatures that lurk there.

 Night falls suddenly here, as all the phosphorescence and luminescent creatures in this undersea world (bubble-crater included), are still diurnally keyed to the sun whose rays have never penetrated to these depths.  Dirk and the doctor set up camp and keep a tense watch, but then, "Dirk heard the report of a gun.  A woman screamed.  Then silence."  (p.136)

Chapter 11:  A Strange City

Dirk and the doctor try to rush to the rescue, but end up having to wait it out till daylight, so they can at least see their hands in front of their faces.  Meanwhile, Dirk sleeps and the doctor is snatched (as it turns out, by a Jogular referred to as "the bos'n," who was leading a group of guardsmen of the usurper king).  But, with Dirk alone again, we now get our first lion kill in this Burroughs story!  A lion attacks Dirk and knocks him out, but Dirk comes to and finds that a Jogular lion's fleshy teeth and jaws can't bite, even though the lion's replicated memory and instincts tell him that he wants to try.  Dirk kills it anyway by multiple stab wounds, which produce very little blood, but it eventually rolls aside quivering, then lies very still.  (p.139)

Other carnivores, insectivores, and even herbivores in this bubble-crater are in the same boat – they can catch their prey, but they can't eat or swallow it.  Their innards are now all solid interlocking cells, with no throat, stomach, or anything else to process the food they still crave.  The human Jogulars in the city are the same, with beverages being heartily quaffed in taverns, then flowing back out of their mouths unnoticed.  (p.145)

The shot that was heard the night before turns out to be Von's discarding of Harry Grube as his accomplice.  Dirk finds Grube's body shot through the back of the head with a .45, and since microorganisms immediately start consuming anything dead here, Grube's bald head and gold teeth confirm his identity.  (p.140)  Dirk then follows the river downward into the center of a half-mile wide circular cavity into which all the rivers cascade – into an abyss.  At the far embankment of this is a city, with architecture that is a mixture of old London, Roman, and late 17th century sailing vessels.  (p.141)  The inhabitants of this city, including most of their clothes, are all of whitish, jelly-like flesh with a single, real eye in the middle of their foreheads, and sightless eyes where the originals were.  (p.142)  These are the Jogular replicas of ancient Roman sailors, 17th and 18th century English seamen, and a few more recent acquisitions of various sorts.  They are all telepathic and voiceless, even the dogs that have silent barks, and the barmaids that sing silent songs.  (p.146)  Their bodies are softish, but still have enough fibrous tissue to stand and move about, even for Jogular men to ride Jogular horses.

Chapter 12:  The Black Falcon Palace

Dirk infiltrates the palace at the center of the city, which has been built to resemble the Black Falcon.  His appearance is not remarked upon, but since he can "hear" the Jogulars communicating telepathically, he has to work at trying to keep the guards from overhearing his thoughts, in turn.  He finds that they communicate both with words and  images (no color – only black, white, and shades of gray).  Some of them even speak a language other than English, and Dirk only catches the images in this case, although some words in the other languages might "sound" familiar.  (p.149)  He searches for Ellen, evades guards, and then gets knocked out by Von, who delivers a single sudden sword blow to his head.  (p.154)

Chapter 13:  The Jogulars

Dirk awakes to find himself in the dungeon with Dr. Kingsley and the Jogular of Roger Stuart, whom we get to know a bit.  It turns out that the presence of the submarine by the wrecked vessels had revealed to the Jogulars in the city the presence of the gold, thus exciting their gold-fever, acquired from the hosts they replicated.  Fecus, a Roman with a badly messed up face (resulting from his replicating a corpse with a crushed head), used the gold to bribe his way to power.  He usurped the throne from Roger (the rightful king by popular acclaim, succeeding a good Roman ruler about a hundred years ago), then had Roger thrown in the dungeon, as a prelude to having him thrown into the Great Falls (which is the abyss into which the rivers cascade).  Also, he is now using undeveloped Jogulars to try to brainwash Barbara Stuart into loving him instead of her husband.

The traitorous Von Benson, it turns out, had been infected with the parasite, and he is now already part Jogular.  He has made a pact with Fecus – for a share in the gold, the girl, and help getting the sub back to the surface.  Ellen is therefore being subjected to the undeveloped Jogulars along with Barbara, to try to convince Ellen she loves Von.  Also, rather cleverly, Von has something that these creatures want – the large stock of morphine now in the flooded storage compartment of the sub!

Chapter 14:  The Traitors

 Dirk and Roger have the dubious pleasure of an interview with Fecus.  The undeveloped Jogular brain-things are explained (p.175), and the room behind the throne where they are attempting to brainwash Ellen and Barbara is seen.  Regarding the morphine:  the Jogulars, being all brain, experience quite an effect from even small amounts of morphine, and enough of them have human memories remaining of such things to make it even more appealing, especially as it now leaves them no hangover!  (p.179)  Von even plans to use his knowledge from having once been a pharmacist's mate to distill more opium from the opium poppies that happen to grow there.  We are now also told the reason that Phil and Willoughby died from the transformation and Von has survived:  quite simply, they were weak or injured to start with, and Von was perfectly healthy.  The chapter ends in the dungeon, where Roger Stuart uses his telepathic influence to cause the rats there (rats the size of cats) to leap on the guard.  (p.186)

Chapter 15:  "I Love You!"

 They escape, amid some fighting, and Dirk cleaves a Jogular from crown to groin.  (p.189)  After wandering around lost in the endless tunnels of the palace, Dirk overhears Ellen proclaiming her love to Von – leaving Dirk to agonize over Ellen's trance-induced proclamation, as he fails to remember about the whole brainwashing thing.  But Dirk then finds Ellen alone and kisses her, and she returns it a dozen times or more, not minding his sweaty, dirt-grimed hair or his blood-stained hands (no mention of Dirk's dungeon breath, however).  It turns out that Ellen was about to throw herself out a window rather than endure more trance sessions or a future life with Jogular-Von, whom she describes as a "soulless monster who would stop at nothing to satisfy its base desires!"  (p.196)  Von returns and is about to shoot Dirk, when Barbara Stuart appears and throws a dagger into Von and drops him.  (p.197)

Queen Barbara Stuart, Ellen's five-times great grandmother, after making this spectacular entrance, tells us she had also been planning her self-destruction.  She had been planning to jump into the Falls, after Fecus had had Roger thrown into them, rather than live without her husband.  (p.199)  Conveniently, Fecus had insisted that Von wear a "little known Roman helmet" that has a face mask, as part of the imminent double-wedding ceremony (of Von to Ellen and Fecus to Barbara), so Dirk now uses it to disguise himself as the would-be bridegroom.

Chapter 16:  Mock Marriage

On their way to Fecus' hall, Ellen and Dirk discuss the nature of the Jogulars and their lives, and the possibility that the Jogulars may have souls is mentioned.  (p.204)  The relative value of the Jogulars as beings in their own right had already been given due philosophic consideration by the doctor, back with Dirk in the dungeon in Chapter 13.  (p.163)

At the wedding, Roger, who had been recaptured, is drugged into giving Barbara to Fecus in marriage, after which Fecus will be free to kill Roger.  Dirk struggles successfully to keep his thoughts from giving him away to the telepathic Fecus and his nearby undeveloped Jogular brains, but the jig is up when Jogular-Von suddenly puts in a reappearance.  Heroic battle ensues, with our heroes attempting escape through the room in back of the throne where the brains are kept.  Dirk believes they have made their escape out of the palace, gotten horses, ridden across a plain, but ... he now finds himself alone on the plain.  Not sure what to believe is real, he begins searching for the tracks of their horses, and is still searching when Fecus' warriors overtake him.  He will find out that the brains had induced an hallucination that Roger, Barbara, and Ellen were with him, when he had actually slammed and locked the door on them, leaving them in the room with the brains to be recaptured.

Chapter 17:  Sacrifice to the Falls

 Here we get the first mention by the doctor of "a mysterious Jogular who wears a mask at all times and maintains a laboratory in the palace.  He is supposed to possess extraordinary scientific knowledge."  (p.219)  This mysterious Jogular is said to be helping Von with plans to get the sub to the surface, as Jogular-Von intends to take Ellen with him back to England!  How he hopes to pass as normal when he has an eye in the middle of his forehead is not mentioned.  Other characters make their appearance:  Jim Peacock, innkeeper, who is friendly to Roger Stuart; Ezekiel, a dwarf stone-cutter who specializes in carving angels, who is loyal to the Queen; Volgus, a guard whose arm Dirk had twisted, who is in service to Fecus.

 Much as his father would, JCB now has Fecus abuse an old religious superstition to justify his having his enemies thrown into the Falls – by claiming them as ritual sacrifices.  This is further explained, but essentially they are a sort of fertility offering.  Jogulars reproduce by periodically casting off cells, and the Jogulars in the city cast their cells into the Falls, from which these cells eventually find their way out to the ocean in search of hosts.  The sacrifice victims will therefore either become hosts themselves to cells already in the abyss, or add their own cells to this font of future Jogulars.  (p.221)  Roger, Dirk, and Dr. Kingsley are the last in the line-up of sacrificial victims walking the plank, overseen by the vengeful Volgus.  The Jogulars that precede them leap unassisted, after expressing their loyalty to King Stuart.  The doctor is next, but he slips and falls, and Volgus kicks him viciously in the face.  It is then that Dirk slips the bonds on his wrists, and much sword-fighting mayhem ensues.  They escape to lead a Stuart-ite uprising against Fecus and his minions, but the tide goes against them.

 They are almost out of hope (all in a very few, densely-packed pages from the plank-walking scene) when the cavalry arrives – fresh troops armed with slick, ultramodern-appearing automatic rifles, led by Chief Engineer Pigeon Ellis and the mysterious man in the mask, who turns out to be Phillip Montague, or at least his equally ingenious Jogular equivalent.  (The mask is to hide where his corpse was injured when a large rock fell on his face when they were burying him, and which the replication process naturally copied.)  They rout the warriors of Fecus, even his bodyguard, at which point the usurper wheels his horse and joins his men in flight.  (p.233)

Chapter 18:  A Quest Ends

It turns out that only the five men in front (Phillip, Ellis, Flobs, Frenchy, and Packard) actually had the rifles.  The rear guard was actually old men and women wearing warrior robes, who had faked it by carrying oil-soaked, smoking broomsticks!  Dirk then dubs them, "The Broomstick Brigade."  Jogular-Wicks and Jogular-Hill are also there with them.  Forgetting the mute stowaway Bucky, who, after all, is now just a head with fins, Frenchy remarks, "All we need now ees poor Willoughby."  And to this, Phillip replies, "I suspect he'll be coming along later."  (p.237)

Phillip then tells of himself, and of how he had been helping Von with his plans to marry Ellen and return her to the surface, but that was before he realized Von was now a Jogular, and that Ellen was not in love with Von.  Phillip had been granted materials and metalworkers by Fecus, because Fecus wanted Phillip to make firearms for him.  After he found out the truth, Phil instead used these resources to make new air cylinders, secure the help of the remaining men on the sub, and then use the rifles they had made to retake the city.

The "Aliens!" connection is now solidified (for those who might not think the meteor would be enough to transport the Jogular microorganisms to the bottom of the ocean), and the convenient pressure at the bottom of the ocean is covered, as well:  the doctor asks Phillip what he knows about the pressure being only that of 30 fathoms, and Phil explains:

Doctor, I had assumed a great meteorite was responsible for the repelling force that created this unique lessening of the hydrostatic pressure, but recently I learned of an ancient Jogular legend that tells of a giant silver-colored vessel that crashed into the ocean's floor, producing the crater in which we now find ourselves.  ...
  I have discovered some objects in the palace laboratory that make me believe there is indeed a space vehicle buried in the earth beneath our feet.  Ancient documents I have found in the royal library indicate that our ancestors, the original brain Jogulars, came from another solar system in a ship that could use the gravitational forces of the universe for propulsion.  (p.242-243)

Phillip also says that the brain Jogulars believe there may be other Jogular colonies somewhere in the ocean depths, due to emanations they are aware of during their meditations – therefore, room for sequels?

 Phil has read Dirk's thoughts, and quite decently says that Ellen is Dirk's now.  Dirk demurs, and says that Ellen must choose for herself, even if her former fiancé is now a mask-wearing Jogular.  There's time left for Von to kidnap Ellen, leaving a (trance-induced) note saying that she has been infected with the parasite and is now sprouting scales as an incipient Jogular, so that she is going away with Von, as they are now two of a kind.  This allows Dirk to agonize a teeny bit more, including creepy thoughts of gills and an eye in the middle of Ellen's forehead.  But he goes after her anyway, to find out if she really loves him or not, as he realizes she may have left only because she didn't think Dirk could be open-minded enough to love her as a Jogular.  He is nearly fooled one more time into some more agonizing, when he hears Ellen's repetition of her trance-proclamation that she loves Von, but then he remembers the very same brainwashing-induced words from before.

 The personal finale after the big finale is now here:  Dirk finds Von and Ellen, and the one-time best friends go mano-a-mano in that long awaited primordial battle over the dame.  To keep the otherwise uneven fight going (since Von is now Jogular-flabby), Von shoots Dirk in the arm, rendering it useless.  Dirk falls over a precipice, pulling Von after him, with Von clinging to the edge and Dirk clinging to Von.  In a satisfying switch, with Von mentally directing Ellen to shoot Dirk in the head, Ellen shoots Von instead – right in his eye.  Then, despite Dirk's large size and one of her hands still being entangled in Von's clothing, Ellen keeps Dirk from falling and helps him climb up.  The truth is revealed – Ellen isn't a Jogular, and she doesn't love Jogular-Phil (she had sensed who it was behind the mask).  The real Phil is dead, and she now loves only Dirk.  It concludes with Dirk holding her tightly with his one good arm, deciding that he doesn't care in the least if the submarine never floated them to the surface.  (p.253)

More on the weaker points about the book (see above, also):

The quick underwater clinch ending, with no definite rescue for the sub or its remaining crew.

No follow-up on the former stowaway mute Bucky, the head with fins.

The spaniel dog is never seen or heard of again, after it doesn't die in the galley with Bucky.

The dwarf stonecutter Ezekiel stays around long enough to start to be interesting, but is then killed offstage.

Frenchy's "Zee's ees zo!" accent, which makes the lapsing "Thee's and Thou's" attempt at an 18th century accent for Barbara and Roger look good – and there's even a footnote (p.229) to try to cover how shaky that is!

It takes a long time to figure out some basic information, all to make it more suspenseful until you do find out

More on the better points about the book (see above, also):

• Once things start happening, they really move along, without overdoing the escapes, captures, and rescues.
• The girl helps save the hero in the end, plus she is only lusted after by one of the villains.  (A look-alike, dagger-throwing, 5x-great grandma is brought in for the other villain to covet.)  And despite Dirk's remark, Ellen doesn't actually faint all that much.
• The phrase, "A Fate Worse Than Death," is never mentioned.
• The clever morphine angle, since the Jogulars are "all brain" – worked in nicely with the doctor's addiction.
• Most of the footnotes (except for the "atomic sub" one).
