“No, I don't think I do. Does it matter? Sometime after six, I should say. Ask Mr. Plenmeller! I met him just as I was starting. He might know when that was.”

“That would have been when he was returning with some papers for your husband?”

Again she laughed. “Yes, were you told about that?”

“I was told he made an excuse to leave the party after tea, and came back half an hour later. I didn't know he had met you, madam.”

She paused, turning her head quickly to look at him. “That sounds as if someone were trying to make mischief! Well, it serves him right! Hoist with his own petard. Were you told why he made an excuse to go away?”

“No, I can't say I was madam. Do you know why?”

“Yes, of course: everyone knew! It was quite atrocious and entirely typical. When they made up two sets after tea, Miss Warrenby was one over, and she elected to sit out. Which meant she would talk to Gavin Plenmeller. So he said he must go home to fetch some papers for my husband. You can't be surprised that he makes enemies.”

“No,” agreed Hemingway. “And you think everyone knew why he went away?”

“Oh, well, everyone who heard him! Mrs. Haswell said that he and Miss Warrenby must keep one another company, upon which he told Mr. Lindale, in what he may have meant to be an undertone but which was all too audible, that this was where he must think fast. Whether Miss Warrenby heard it, I don't know: I did! Here we are: this is the estate room. Bernard, are you very busy? I have brought Chief Inspector Hemingway to see you.”

Two steps led up to the open door of the room, which was a large, square apartment, severely furnished with a roll-top desk, a stout table, some filing cabinets, and several leather-seated chairs. A map of the estate hung on one wall, and a door at one side of the room gave access to another and smaller office. The Squire was seated at the table, official forms spread before him. He looked up under his brows, and favoured Hemingway with a hard stare before rising to his feet. “Scotland Yard?” he said brusquely. “You ought to be resting, Rosamund.”
