“That’s the matter in a nutshell,” agreed the inspector. He turned to Mrs. Ackroyd. “Which of the servants would come in here yesterday evening?”

“I suppose the housemaid would turn down the bed.”

“Who is she? What do you know about her?”

“She’s not been here very long,” said Mrs. Ackroyd. “But she’s a nice ordinary country girl.”

“I think we ought to clear this matter up,” said the inspector. “If Mr. Ackroyd paid that money away himself, it may have a bearing on the mystery of the crime. The other servants all right, as far as you know?”

“Oh, I think so.”

“Not missed anything before?”
