“Yes, that’s the question. Who had the house before you?”

“A retired sea captain called Ferguson.”

“Anything remarkable about him?”

“Not that ever I heard of.”

“I was wondering whether he could have buried something. Of course, when people bury treasure nowadays they do it in the Post-Office bank. But there are always some lunatics about. It would be a dull world without them. At first I thought of some buried valuable. But why, in that case, should they want your furniture? You don’t happen to have a Raphael or a first folio Shakespeare without knowing it?”

“No, I don’t think I have anything rarer than a Crown Derby tea-set.”
