"That's a very useful man," said the millionaire as Goby went out and his secretary came in. "In his own line he's a specialist."

"What is his line?"

"Information. Give him twenty-four hours and he would lay the private life of the Archbishop of Canterbury bare for you."

"A useful sort of chap," said Knighton, with a smile.

"He has been useful to me once or twice," said Van Aldin. "Now then, Knighton, I'm ready for work."

The next few hours saw a vast quantity of business rapidly transacted. It was half-past twelve when the telephone bell rang, and Mr. Van Aldin was informed that Mr. Kettering had called. Knighton looked at Van Aldin, and interpreted his brief nod.

"Ask Mr. Kettering to come up, please."

The secretary gathered up his papers and departed. He and the visitor passed each other in the doorway, and Derek Kettering stood aside to let the other go out. Then he came in, shutting the door behind him.

"Good morning, sir. You are very anxious to see me, I hear."

The lazy voice with its slightly ironic inflection roused memories in Van Aldin. There was charm in it—there had always been charm in it. He looked piercingly at his son-in-law. Derek Kettering was thirty-four, lean of build, with a dark, narrow face, which had even now something indescribably boyish in it.
