"The lady's been away about three days, sir," he said, with the stolidity of a policeman giving evidence. "Couldn't tell me when she'd be back. Hadn't left any instructions about the heating apparatus for the new peach-house she is having built. The butler believed the firm who were constructing the house were to put in the plant. He said she left after tea with her maid and luggage for a journey in a motor. Not her own car. He thought it must have been one she hired from Wednesford. I have been round the garages, but no one from Redwithy has hired a car. That's why I am a bit late, sir."

The chief turned to Ruxton, who was eagerly intent upon the man's information.

"I sent him"—indicating the plain-clothes man—"as a heating expert from a well-known horticultural firm."

Ruxton nodded.

"You saw the butler—a foreigner?"

"Yes, sir."

"Did you gather an—impression from him?"

"He seemed straightforward and quite ready to talk, sir. I'm sure he knew nothing more, and seemed to believe what he said."

"There's nothing else?"

"No, sir, I think not. The place seemed all reg'lar. You see, sir, I've often 'ad to keep an eye on it when the lady's been away holiday-makin', and during the war. You see, she's a foreigner. So I know it pretty well, though it don't know me. One thing that struck me he was speaking truth was there was a tidy bunch of letters on a hall table. Might have been an accumulation."
