"Ah!" said Mr. Pritchard. "I may say that I have been expecting this. A similar suggestion was made to me earlier by Mr. Murbles, and I then told him that my client preferred not to entertain the idea. You will permit me to add, Lord Peter, that the reiteration of this proposal by you, after your employment to investigate the facts of the case in the interests of the other party, has a highly suggestive appearance. You will excuse me, perhaps, if I warn you further that your whole course of conduct in this matter seems to me open to a very undesirable construction."

Wimsey flushed.

"You will perhaps permit me, Mr. Pritchard, to inform you that I am not 'employed' by anybody. I have been requested by Mr. Murbles to ascertain the facts. They are rather difficult to ascertain, but I have learned one very important thing from you this afternoon. I am obliged to you for your assistance. Good morning."

The beady-eyed clerk opened the door with immense politeness.

"Good morning," said Mr. Pritchard.

"Employed, indeed," muttered his lordship, wrathfully. "Undesirable construction. I'll construct him. That old brute knows something, and if he knows something, that shows there's something to be known. Perhaps he knows Oliver; I shouldn't wonder. Wish I'd thought to spring the name on him and see what he said. Too late now. Never mind, we'll get Oliver. Bunter didn't have any luck with those 'phone calls, apparently. I think I'd better get hold of Charles."

He turned into the nearest telephone-booth and gave the number of Scotland Yard. Presently an official voice replied, of which Wimsey inquired whether Detective-Inspector Parker was available. A series of clicks proclaimed that he was being put through to Mr. Parker, who presently said: "Hullo!"

"Hullo, Charles. This is Peter Wimsey. Look here, I want you to do something for me. It isn't a criminal job, but it's important. A man calling himself Oliver rang up a number in Mayfair at a little after nine on the night of November 10th. Do you think you could get that call traced for me?"

"Probably. What was the number?"

Wimsey gave it.
