“Will you ask Sir James if I can see him for a few minutes? I have an important message for him.”

The butler retired, returning a moment or two later.

“Sir James will see you. Will you step this way?”

He ushered them into a room at the back of the house, furnished as a library. The collection of books was a magnificent one, and Tuppence noticed that all one wall was devoted to works on crime and criminology. There were several deep-padded leather arm-chairs, and an old-fashioned open hearth. In the window was a big roll-top desk strewn with papers at which the master of the house was sitting.

He rose as they entered.

“You have a message for me? Ah”—he recognized Tuppence with a smile—“it’s you, is it? Brought a message from Mrs. Vandemeyer, I suppose?”

“Not exactly,” said Tuppence. “In fact, I’m afraid I only said that to be quite sure of getting in. Oh, by the way, this is Mr. Hersheimmer, Sir James Peel Edgerton.”

“Pleased to meet you,” said the American, shooting out a hand.

“Won’t you both sit down?” asked Sir James. He drew forward two chairs.

“Sir James,” said Tuppence, plunging boldly, “I dare say you will think it is most awful cheek of me coming here like this. Because, of course, it’s nothing whatever to do with you, and then you’re a very important person, and of course Tommy and I are very unimportant.” She paused for breath.
