“To repeat myself, Holmes, who did the voice actually belong to?”
“Ah, that can wait, Watson. Our descent is slowing. Soon we will look into Barstow’s lair.” He shot me a glance. “His tomb?”
The crane operator stopped paying out the hawser as we bumped against the bottom. Just a yard or so away lay the diving bell — the twin of the one we now sat in. Though confoundedly gloomy down here I could make out some detail. Kelp grew from the iron cylinder. The rounded shape was suggestive of some monstrous skull covered with flowing hair. Spars from the wreck had enclosed the diving bell like the bars of a cage, trapping it that fateful day five years ago. A grip so tight that the haulage gear had snapped the hawser as it strove to raise the doomed submersible to the surface.
Those black waters would reveal little. Not until Holmes closed a switch. The moment he did so, a light sprang from the lamp fixed to our craft.
“Now we can see who resides inside the Pollux.” Holmes took a deep breath as his keen eyes made an assessment. “Are we of the same opinion of the occupant?”
Likewise, I took a steadying breath. I peered through our porthole and into the porthole of the craft trapped by the stricken bullion carrier, Fitzwilliam. “Now I see. But I don’t understand how he speaks to us.”
“Confirm what you observe, Watson.”
“A cadaver. Partly mummified as a result of being confined in an airtight compartment. Inert. Lying on the bench at the rear of the vessel.”
“The man would have been dead within a few hours of being marooned without an air supply. Is that not so?”
“Agreed.”
“Notice that the hawser has been retrieved and snakes up to the surface. But notice, equally, that the telephone cable has been snapped at the point it should enter the Pollux. Barstow, alive or dead, never made so much as a single call once that cable had parted from the apparatus within his diving bell.”
“So, who is responsible?”
“A creature of flesh and blood!” If it weren’t for the confines of the diving bell an excited Sherlock Holmes would have sprung to his feet. “Miss Claudine Millwood! Twin sister of that man’s widow.” He inhaled deeply, his nostrils twitching in the manner of a predator catching scent of its prey. “You see, Watson, I shall one day write a monograph on an especially rarefied subject. Yet one which will be invaluable to police when interrogating suspects or, more importantly, discussing certain matters, within the hearing of a suspect. I have observed, during my career as a consulting detective, that the eyes of a human being move in such a prescribed way that they hint at what they are thinking. Strongly hint at that! With practice, one can become quite adept at reading the eye-line of a man or woman.”
“Therefore, you studied Miss Claudine Millwood when you questioned Mrs. Barstow?”
“That I did, sir. In this case, as I spoke to the widow, I also took careful note of the direction of Miss Millwood’s eye-line. When I mentioned Mr. Barstow by name the woman’s gaze became unfocussed, yet directed slightly downward and some degrees off centre to her left. Trust me, Watson, how we arrange our limbs and direct our gaze reveals volumes to the competent observer.”
“Therefore you could glean her unspoken thoughts?”
“To a degree. The direction of her gaze and the unfocussed eyes told me that Miss Millwood was in the process of recalling a memory that is not only secret to her, but one she knew would shock or revolt right-minded individuals. That was enough to arouse my suspicions.”
“And you divined this by reading the eye-line? Remarkable!”
“Just as you, a medical man, can diagnose an illness from subtle symptoms. Moreover! The woman couldn’t bear to hear her own sister reveal that private, intimate name, which, once upon a time, she murmured into her husband’s ear. A name that Claudine Millwood, did not know.”
“Millwood was in love with her sister’s husband?”
“Without a shadow of doubt. Whether that love was reciprocated or not we don’t know.”
“And during the years Barstow lay in that iron tomb the love grew.”
“Indeed! The love grew — and it grew malignantly. That obsessive love took on a life of its own. Millwood projected thoughts from her own mind into the telephone apparatus. She imitated the late Mr. Barstow.”
“Why didn’t she want us to venture down here?”
“That would have destroyed the fantasy. We would have returned to the surface, but not, however, with an account of finding a handsome young man full of miraculous life, still trapped within the diving bell. No! We would have returned with the grim fact that we gazed upon a shrivelled corpse.” Holmes snapped his fingers. “We would have ruptured the fantasy. The woman has incredible mental powers, certainly — yet she is quite mad.”
“So she killed the crew of the Castor yesterday?”
“In order to prevent them describing what we, ourselves, now see.”
“Holmes, Captain Smeaton claimed they were frightened to death.”
“Miss Millwood will have conjured some terrible chimera, no doubt.”
“And the shadow that attacked us as we descended?”
“Millwood.”
“Then she won’t allow us to return to the surface?”
“No, Watson. She will not.”
“Therefore, she won’t stop at yet more slayings to keep her fantasy alive — that Barstow is immortal?”
“Indubitably. However, we do have recourse to the telephone.” He picked up the handset.
“But the woman fell in a dead faint. I checked her myself; she’s deeply unconscious.”
“My good doctor, I don’t doubt your assessment. However, recall the essays of Freud and Jung. Aren’t the leviathans of deep waters nothing in comparison to those leviathans of our own subconscious?’
Holmes turned the handle of the telephone apparatus. At that precise instant, a dark shape sped through the field of electric light. This time the walls didn’t impede its progress. A monstrous shadow flowed through the iron casing of the diving bell. Instantly it engulfed us. We could barely breathe as tendrils of darkness slipped into our bodies, seeking to occupy every nerve and sinew.
“Watson, I am mistaken! The woman’s attacks are far more visceral than I anticipated.”
“She’s invading the heart. Those men died of heart failure. Ah…” A weight appeared to settle onto my ribs. Breathing became harder. My heart thudded, labouring under the influence of that malign spirit. “Holmes, you must tell the … the captain to distract her. Her flow of unconscious thought must be disrupted.”
Holmes grimaced as he struggled to breathe. “A shock … how best to administer a shock?”
“Electricity.”
With a huge effort Holmes spoke into the telephone. “Captain Smeaton. Ah… I…”
“Mr. Holmes?”
“Listen. We will soon be dead. Do as I say … uh … don’t question … do you understand?”
“I understand.” The man’s voice was assured. He would obey.
“Is Millwood there?”
“Yes, she’s still unconscious.”
“Then rip the power cables from an electrical appliance. Apply the live wire to her temple.”
“Mr. Holmes?”
“Do it, man … otherwise you haul up two more corpses!”
Then came a wait of many moments. Indeed, a long time seemed to pass. I could no longer move. The shadowy presence coiled about the interior of the diving bell as if it were black smoke. We sagged on the bench, our heartbeats slowing all the time. Another moment passed, another nudge toward death. That shadow was also inside of us, impressing itself on the nerves of the heart.
