"How clever you are!" I said.

"Yes—I'm clever—when I'm not a fool. Don't think, anyhow, that you can beat me in a battle of brains. I've come on board this boat to succeed, and I will succeed in one of two ways, I don't care a hang which. But nothing on God's earth can hold me back from one or the other—least of all, can you. Why, you can ask any question you please, and I'll answer. I'll tell the truth, too—for the more I say, and the more you're shocked, the more helpless you are—do you see?"

"No, I don't see," I drew her on.

"Don't you guess yet who I am?"

"I've guessed what you were—a German spy."

"That's ancient history. One must live—and one must have money—plenty of money. I must! And I've had it. But it's gone from me—like most good things. Now I must have more—a lot more. Or else I must die. I don't care which. But others will care. I'll make them."

Looking at her, I doubted if she had the power; though she must have had it in lost days of gorgeous youth. Yet again I remained silent. I saw that she was leading up to something in particular, and I let her go on.

"You're not much of a guesser," she said, "so I'll introduce myself. Lady-who-thinks-she's-going-to-marry Roger Fane, let me make known to you the lady who has married him—Mrs. Fane, née Linda Lehmann. I've changed my name since, more than once. At present I'm Katherine Nelson. But Linda Lehmann is the name that matters to Roger. You're nothing in looks, by the by, to what I was at your age. Nothing!"

If my knees had been weak before, they now felt as if struck with a mallet! She might be lying, but something within me was horribly sure that she spoke the truth. I'd never heard full details of Roger Fane's "tragedy," but Mrs. Carstairs had dropped a few hints which, without asking questions, I'd patched together. I had gleaned that he'd married (when almost a boy) an actress much older than himself; and that, till her sudden and violent death after many years—nine or ten at least—his life had been a martyrdom. How the woman contrived to be alive I couldn't see. But such things happened—to people one didn't know! The worst of it was that I did know Roger Fane, and liked him. Besides, I loved Shelagh, whose happiness was bound up with Roger's. It seemed as if I couldn't bear to have those two torn apart by this cruel creature—this drunkard—this spy! Yet—what could I do?

At the moment I could think of nothing useful, because, if she was Roger's wife, her boast was justified: for his sake and Shelagh's she mustn't be handed over to the police, to answer for any political crime I might prove against her—or even for trying to burn down the Abbey. Oh, this business was beyond what I bargained for when I engaged to "brighten" the trip on board the Naiad! Still, all the spirit in me rallied to work for Roger Fane—even to work out his salvation if that could be. And I was glad I'd let the woman believe I was Shelagh Leigh.
