"Oh, no," Grant said. "I found it out quite accidentally. It is of no consequence. Is your wife better?

"Yes, I think so. She has not been at home since the inquest. She is at Eastbourne with the other sister the one you met, I think."

Still more puzzled, Grant made his way back to the Yard. He pressed the button on his desk and said to the man who answered it, "I want some one for special work. Is Simpson in?"

"Yes, sir."

"Send him in."

A fair and freckled man of medium height arrived; he had the pleased, alert air of a terrier who is waiting for some one to throw a stone. To him Grant said:

"At 54 Lemonora Road, Golder's Green, live a Mr. and Mrs. Ratcliffe. I want to know what terms they are on — with each other, I mean. Also anything else you can learn about the household. The gossipier the better. I know all about his business, so you needn't waste time on that. It's his home affairs that I want to know about. You can use any method you like as long as you keep within the law. Report to me tonight whether you have got anything or not. Is Mullins in the Yard just now?" Yes, Simpson had seen him as he came up. "Well, send him to me."

Mullins was not freckled, and he looked rather like a verger. "Good morning, sir," he said, and waited.

"Good morning, Mullins. From now until further notice you are a pedlar. You make an excellent Italian, but I think perhaps you had better be British. It is less conspicuous. I'll give you a chit to Clitheroe on Lowndes Street, and he will give you the kind of stock I want. Don't sell more than you can help. And I don't want you to come back here. Meet me in the alley by Clitheroe's in an hour from now. Can you manage it in an hour?"

"I think so, sir. Am I young or old?"
