It must be conceded that for an amateur, the major set about his unaccustomed task in a very methodical manner. He offered a reward of five hundred pounds for the detection of the murderer, and a further sum of the like amount to anyone who should discover the thief who had desecrated the chamber of death. These munificent rewards set everybody on the alert, and Jen, without putting down actual money, thus became possessed of some hundreds of spies who would bring him any information likely to assist him in his investigation. Also, the major examined all the servants in the house. He questioned Sampson, the young policeman who had been in the kitchen on the night when the body had been stolen, and finally he paid a visit to the police office at Deanminster, where he saw Mr. Inspector Arkel.

"Well, Arkel," said Jen, after the first greetings were over, "have you any clew?"

"No, major," replied Arkel, rather gruffly, for disappointment was beginning to tell on his temper, "nor are we likely to find any until that servant of yours regains his senses. How is he now?"

"In a state of high fever, poor soul," said Jen, with a depressed look. "He does nothing but rave. Yet, in all his wild talk he never lets slip a single word likely to help us."

"That's a pity, major. By the way, I questioned Dr. Etwald about the matter, and he is of opinion that the man was stunned by a blow on the head."

"I know that. I can only suppose that Jaggard fell asleep at his post and woke up in time to see the men getting in by the window. A struggle would then ensue, and he would be struck on the head, as Etwald supposes."

"I don't agree with that theory. There are flaws in it."

"Yes?" queried Jen, eagerly. "I am open to correction. Please go on."

"We will proceed on the questions and answers system," said Arkel, precisely, "and thrash out the matter in that way. You were in the library on that night?"

"Yes, I saw all was right in the house at twelve o' clock, and I slept on in my chair from that hour until three."
