Joan shook her head.

“He said he’d let me know where he was staying, but he hasn’t written. Perhaps he hasn’t settled down yet. He may be staying at an hotel for a day or two.”

“Please ring me up as soon as he sends word.”

Joan promised to do this, and Sir Clinton continued:

“By the way, Inspector Armadale wishes to take the finger-prints of every one in the house. Would you mind setting an example and having yours taken along with the rest? If you do it, then it will be easier for us to get the others. They won’t be suspicious when they hear that it’s a general inquisition.”

Both Joan and Michael consented without ado.

“The Inspector will be with you in a moment or two,” Sir Clinton said, as he took his leave. “Just a word with you, Inspector.”

Armadale followed him from the room.

“Now, Inspector, there’s a lot for you to do yet. First of all, get these finger-prints. Then telephone to London and get Kessock’s business address. As soon as you get it, let me know.”

“But you got his address from the correspondence, sir, surely. It’s in Fifth Avenue.”
