“To move rapidly is always incumbent upon the adventurer, if he is to be successful in eluding awkward inquiry. He never writes to the child, I suppose?” Frank asked, as Aggie at that moment passed the window.

“Oh, yes, very often. But he always encloses her letter to me. He never gives his address to her, for fear, I suppose, that it should fall into other hands. I wired to his rooms in Paris a week ago, but, as yet, have received no response. His rooms in London are closed. I was up there on Thursday. Why he keeps them on when he’s away for years at a time, I can never understand.”

“Probably sub-lets them, as so many fellows do,” Farquhar suggested, “yet it’s unfortunate we can’t get into touch with him.”

“Miss Griffin is acquainted with him—I wonder if she knows his whereabouts?” remarked Diamond quite innocently.

“She knows him!” Frank echoed in surprise. “Are you quite sure of that?”

“Quite. She told me so.”

“How could she know a man who is admittedly an outsider?” asked Frank.

“My dear Mr Farquhar,” he laughed, “your modern girl makes many undesirable acquaintances, especially a pretty go-ahead girl of Miss Griffin’s type.”

Frank bit his lip. This friendship of Gwen’s with the man Mullet annoyed him. What could she possibly know of such a man? He resolved to speak to her about it, and make inquiry into the circumstances of their acquaintance.

He must warn her to have nothing to do with a man of such evil reputation, he thought. Little did he dream that this very man whom the world denounced as an outsider had stood the girl’s best and most devoted friend.
