The side of the ship made an opaque belt of shadow on the darkling glassy shimmer of the sea.  But I saw at once something elongated and pale floating very close to the ladder.  Before I could form a guess a faint flash of phosphorescent light, which seemed to issue suddenly from the naked body of a man, flickered in the sleeping water with the elusive, silent play of summer lightning in a night sky.  With a gasp I saw revealed to my stare a pair of feet, the long legs, a broad livid back immersed right up to the neck in a greenish cadaverous glow.  One hand, awash, clutched the bottom rung of the ladder.  He was complete but for the head.  A headless corpse!  The cigar dropped out of my gaping mouth with a tiny plop and a short hiss quite audible in the absolute stillness of all things under heaven.  At that I suppose he raised up his face, a dimly pale oval in the shadow of the ship’s side.  But even then I could only barely make out down there the shape of his black-haired head.  However, it was enough for the horrid, frost-bound sensation which had gripped me about the chest to pass off.  The moment of vain exclamations was past, too.  I only climbed on the spare spar and leaned over the rail as far as I could, to bring my eyes nearer to that mystery floating alongside.

As he hung by the ladder, like a resting swimmer, the sea lightning played about his limbs at every stir; and he appeared in it ghastly, silvery, fishlike.  He remained as mute as a fish, too.  He made no motion to get out of the water, either.  It was inconceivable that he should not attempt to come on board, and strangely troubling to suspect that perhaps he did not want to.  And my first words were prompted by just that troubled incertitude.

“What’s the matter?” I asked in my ordinary tone, speaking down to the face upturned exactly under mine.

“Cramp,” it answered, no louder.  Then slightly anxious, “I say, no need to call anyone.”

“I was not going to,” I said.

“Are you alone on deck?”

“Yes.”

I had somehow the impression that he was on the point of letting go the ladder to swim away beyond my ken—­mysterious as he came.  But, for the moment, this being appearing as if he had risen from the bottom of the sea (it was certainly the nearest land to the ship) wanted only to know the time.  I told him.  And he, down there, tentatively: 

“I suppose your captain’s turned in?”

“I am sure he isn’t,” I said.

He seemed to struggle with himself, for I heard something like the low, bitter murmur of doubt.  “What’s the good?” His next words came out with a hesitating effort.

“Look here, my man.  Could you call him out quietly?”

I thought the time Had come to declare myself.

“I am the captain.”

I heard a “By Jove!” whispered at the level of the water.  The phosphorescence flashed in the swirl of the water all about his limbs, his other hand seized the ladder.
