"'Now will you promise?' she repeated. I couldn't—for I should not have kept my word. She looked at me a second. I saw in her eyes that she was going to do the thing, and I jumped at her—but I was too late. She nearly drained the phial. And she'd hardly flung it away before she was dead—with an awful, twisted face—and that cry. If I hadn't caught her, she'd have fallen with a crash. This is the end of things for me."
"Oh, no—don't say that!" I begged.
"What else is there to say? There she lies, dead in my cabin. There's prussic acid on the floor—and the phial broken. The room reeks of bitter almonds.

I had to draw a long breath before I could answer. I needed air! "You're right." I said. "To give the body to the sea would make things worse. You couldn't be sure it would not be found, and the woman traced by the police. If they discovered who she was—that she'd been your wife—you would be suspected even if nothing were proved through those who saw a veiled woman come on board."
"That's what I meant. Yet you must see that even with your testimony, my innocence can't be proved if the story of this night has to be told."
"I do see. You might not be proved guilty, but you'd be under a cloud. Shelagh would still want to marry you. But she's very young, and easy to break as a butterfly. The Pollens——"
