"Why should he do it?" I asked.

"Precisely what I should wish to ask you. If he had any such misgivings, why could he not come and tell me direct?"

"Will you speak to him about it?"

"There again I am in doubt. He might choose to deny that he wrote it."

"At any rate," said I, "this warning is meant in a friendly spirit, and I should certainly act upon it. Are the present precautions enough to insure you against robbery?"

"I should have thought so. The public are only admitted from ten till five, and there is a guardian to every two rooms. He stands at the door between them, and so commands them both."

"But at night?"

"When the public are gone, we at once put up the great iron shutters, which are absolutely burglar-proof. The watchman is a capable fellow. He sits in the lodge, but he walks round every three hours. We keep one electric light burning in each room all night."

"It is difficult to suggest anything more—short of keeping your day watches all night."

"We could not afford that."
