He was on the point of beginning, and then shook his head, doubtfully.

"Don't," said I. "It is all the same to me. After all, it is better
to keep your secret. There's nothing gained but a little relief
if I respect your confidence. If I don't--well?"

He grunted undecidedly. I felt I had him at a disadvantage, had caught
him in the mood of indiscretion; and to tell the truth I was not curious
to learn what might have driven a young medical student out of London.
I have an imagination. I shrugged my shoulders and turned away.
Over the taffrail leant a silent black figure, watching the stars.
It was Montgomery's strange attendant. It looked over its shoulder
quickly with my movement, then looked away again.

It may seem a little thing to you, perhaps, but it came like a sudden
blow to me. The only light near us was a lantern at the wheel.
The creature's face was turned for one brief instant out of the dimness
of the stern towards this illumination, and I saw that the eyes
that glanced at me shone with a pale-green light. I did not know then
that a reddish luminosity, at least, is not uncommon in human eyes.
The thing came to me as stark inhumanity. That black figure with its
eyes of fire struck down through all my adult thoughts and feelings,
and for a moment the forgotten horrors of childhood came back to my mind.
Then the effect passed as it had come. An uncouth black figure
of a man, a figure of no particular import, hung over the taffrail
against the starlight, and I found Montgomery was speaking
to me.

"I'm thinking of turning in, then," said he, "if you've had enough
of this."
