"Why do you say that?"

"Because I have seen them together, and am not entirely blind, Watch
them now--she scarcely responds to his words."

His eyes rested for a moment on the two, but he only shook his head
moodily.

"No one knows what is in the heart of a woman, Carlyle. Sanchez is
fairly young, handsome in a way, and adventurous. Just the sort to
attract a young girl, and he possesses an easy tongue. More than that,
I have lost faith in him. He is not a gentleman."

"You surely must have reason for those words, sir," I exclaimed in
surprise. "He has revealed to you his true nature during the voyage?"

"Unconsciously--yes. We have had no exchange of words, no controversy.
He is even unaware that I have observed these things. Some were of
very small moment, perhaps unworthy of being repeated, although they
served to increase my doubt as to the man's character. But two
instances remain indelibly stamped on my mind. The first occurred when
we were only three days at sea. It was at night, and the two of us
chanced to be alone, on deck. I was reclining in the shadow of the
flag locker, in no mood for conversation, and he was unaware of my
presence as he tramped nervously back and forth. Suddenly he stopped,
and reached over into the quarter-boat, and when he stood up again he
had the Captain's pet cat in his hands. Before I dreamed of such a
thing he had hurled that helpless creature into the water astern."

"Good God! an act of wanton cruelty."
