“I’m glad you called, Inspector,” he exclaimed. “I was going up to the hotel to look for you. This is a terrible development.”

“You’ve heard then, Dr. Emerson?”

“Just this moment. I met Kent and he told me. It is an amazing affair, almost incredible. What does it all mean, Mr. French? Can you understand it?”

“I am afraid, sir, it means what I said on my last call; that Mr. Giles was murdered.”

Dr. Emerson made an impatient gesture.

“But good gracious, man, that doesn’t explain it! Suppose he was murdered: where is his body? Have you a theory?”

French hesitated. He felt tempted to disclose his suspicions to this old man, whose interest and good faith were so self-evident. But his habit of caution was too strong.

“I have a theory, Dr. Emerson,” he answered, “but so far it is only a theory and I don’t like to discuss it until I am reasonably sure it is true. I shall know in a short time and then I will tell you. In the meantime perhaps you will excuse me. But I want to ask you one more question. Roper saw you about the funeral arrangements?”

“Yes. He said that Giles had given him some money for the purpose and that he would see that the best use was made of it.”

“You thought it necessary, I understand, to have the coffining done without delay?”
