"Thanks for the explanation," I replied with more coolness than I felt. "As for 'Jenny'—well, before I ask more questions I'll tell you what I think. 'Jenny' is the woman for whose sake you took up your profession. You'd lost, and wanted to find her. Now, you have found her—or rather, her fingerprints—unmistakable, because they happen to be those of her left hand. Rather than get her into trouble, you'd sacrifice my interests."

Teano remained dumb as the impish child, when I finished and waited for him to speak; so I went on. "I don't want to hurt a woman; yet you see I know so much I can carry on this case without you. Suppose we work together? I'll begin by laying my cards on the table. I can save you the trouble of a search if I choose. I know where 'Jenny' is, and can take you to her."

"You—you're bluffing!" Teano stammered.

"I swear I'm not. Luckily you're a private detective. The police needn't get an inkling of this case, unless you fail me, and I turn to them. All I want is to find out who instigated the affair of night before last. Who carried it out isn't so important to me, though it may be to you. And by the by, has 'Jenny' any personal interest in a little boy of four or five who is dumb?"

"My God!" broke out the detective.

"Don't you think I can be as useful to you as you can to me?" I insinuated. "Why not be frank about 'Jenny'? I promise to hold every word in confidence. Hang up that receiver. You'd better sit down or you'll fall! Now, let's have this out."

The man was at my mercy; yet I knew he was no traitor. "Probably," I reflected, "I'd have done the same in his place."

We sat facing each other, across the bare little table; and Teano began the story of Jenny. There was drama in it, and tragedy, though as yet the story had no end. The sad music was broken; but I began to see, as he went on, that he and I might find a way of ending it, on a different key.

Paul Teano and his sister had come to relatives in New York when he was nineteen and she twelve. That was ten years ago. Paul was now a naturalised American citizen, but at the time of the Italian war in Tripoli he hadn't taken out his papers. There had been other things to think of—such as falling in love. In those days Paul was a budding newspaper reporter. He had gone to "get" a fire, and incidentally had saved a girl's life. Her name was Jenny Trent. It was a case of love at first sight with both. The mother took lodgers, and Teano became one. In a fortnight, Jenny and he were engaged in spite of a rival with money and "position"—that of a bank clerk.

Mrs. Trent wanted Jenny to marry Richard Mayne, and Jenny had vaguely entertained the idea before she met Teano. There was something mysterious and different from the men she had known, about Mayne, which piqued her interest. But the mystery ceased to attract her after the Italian's appearance. Teano, afraid of Mrs. Trent's weakness for Mayne—or his presents, would have married Jenny at once, and trusted to luck for a living; but the girl's mother fell ill, and while Jenny was nursing her, Italy's war broke out. Paul was called to the colours, and sailed for "home" with thousands of other reservists. It was hard luck, and harder still to be wounded and taken prisoner in his first battle. Teano's adventures with his Arab captors would make a separate story, as exciting as Slatin's though not so long, for he suffered only a year and six months' imprisonment. At the end of that time he escaped, made his way to Sicily, and thence back to America as stoker in an Italian ship. His first thought was to see Jenny; but at Mrs. Trent's he found himself taken for a ghost. The report had come that he was dead; and Mrs. Trent had "thought it best" for Jenny to accept Dick Mayne. "For Heaven's sake, keep away," pleaded her mother. "She's not happy with Dick. There was trouble at the bank, and he lost his job. Jenny's wretched. But she's got a baby boy to live for—a poor little thing, born dumb. The sight of you will make things harder."
