“So that when you are out the house is deserted?”

“Absolutely, unless Grey is about in the yard. He was up at the station fetching some stuff this evening and didn’t get back till about nine. Gunnet was here then.”

“Could any one get in easily?”

“Quite. There is nothing here to steal. It’s only occasionally, when there’s money in the house, that I lock the front door.”

The Sergeant was about to speak again when Leslie interrupted him.

“I’ve just remembered. I forgot it till just now. The door was wide open when I came in. I’ve never found it like that before.”

“It was unlocked when you went out?”

“Yes, but it was latched. I always shut it. It’s a good latch, too.”

“Were you about the premises at all this afternoon, Mr. Leslie?”

So far, except for the Constable and his busy pencil in the background, the interrogation had been more or less friendly and informal. Now there was an official ring in the Sergeant’s voice that made Leslie look carefully to his answer.
