"Yes." Frank looked up. "She's a sort of aunt, too," he said unguardedly, flushing as he remembered that he could claim no real relationship with any one. "Her sister was my—mother. I don't know who my father was—exactly. I know he was called Leo, but——"

"Leo!" Leyburn started. It was with difficulty he could keep himself from shouting the name. "Leo—you said? Then you are——" It was on the tip of his tongue to tell Frank he was Hendrie's son. But a sudden inspiration checked the impulse.

"I am—what?" demanded Frank, caught by the others excitement.

But Leyburn was equal to the occasion.

"Not necessarily, though," he said, with an assumption of thoughtfulness. "I was going to say Italian. Maybe Leo was just his first name."

Frank shook his head.

"I don't know. I don't think I'm Italian, though," he said unsuspiciously. "You see, Mrs. Hendrie is American, as, of course, was my mother. She had been an actress. Audrey Thorne, I think she called herself, but her real name was Elsie Hanson. Still, these details can't interest you," he finished up a little drearily.

Leyburn stared out of the window for some moments. He was thinking hard. He was piecing all he had just learned together, and striving to see how he might turn it all to account in the purpose he had in his mind. If he had been amazed before on learning the name of the man who had injured Frank—amazed, and fiendishly delighted, it was nothing to his feelings now. Hendrie, Frank's father! Audie's son! Audie! Yes, more than ever Frank must be enlisted in this work. It would delight his, Leyburn's, revengeful nature if Hendrie could be made to suffer through his own son. It was a good thought, and very pleasant to him.

He turned a smiling, kindly face upon his victim.

"It's all devilish hard luck on you, boy—to be born, in a manner of speaking, without father or mother. The world certainly owes you a big debt. A debt so big you'd wonder how it could ever pay it. But the world has its own little ways of doing things. It's sometimes got a queer knack."
