"Thanks awfully. It encourages me extremely. Charing Cross seems to be a haunt of his. He 'phoned from there on the evening of the tenth, you know."
"So he did."
"I'll tell you what we'd better do, Fentiman. The thing is getting rather serious. I propose that you should go and keep an eye on Charing Cross station. I'll get hold of a detective——"
"A police detective?"
"Not necessarily. A private one would do. You and he can go along and keep watch on the station for, say a week. You must describe Oliver to the detective as best you can, and you can watch turn and turn about."
"Hang it all, Wimsey—it'll take a lot of time. I've gone back to my rooms at Richmond. And besides, I've got my own duties to do."
"Yes, well, while you're on duty the detective must keep watch."
"It's a dreadful grind, Wimsey." Fentiman's voice sounded dissatisfied.
"It's half a million of money. Of course, if you're not keen——"
"I am keen. But I don't believe anything will come of it."
