“Bit gone here,” he said. “I’ve thought so for some time. Poor old chap, so that’s why he had to give up and come down here. In the family, very likely. He’s got a nephew who’s quite off his crumpet.”

“Yes. Hasn’t he ever mentioned him to you? Quite docile, I believe, and all that, but mad as a hatter, poor lad.”

“Who told you that?”

“Jump in, Inspector,” I said, opening the door of the car. “We’ll go up to The Larches together, and acquaint our Belgian friend with the latest news.”
