"The devil you did!"

"I did.—But it may turn out that Perry, or somebody else, or several other people, wore rubber shoes, or rubber-soled shoes last night. Negroes always have large feet."

"Well, I hope my man's found this Perry nigger," said the chief. "He's the fellow we want."

"And yet," ruminated Bristow, "what young Morley said is interesting enough—two quarreling sisters living together—one decked in jewels, the other deprived of them—the jewels gone this morning." He smiled and waved his hands comprehensively. "As long as it is a mystery, let's have it a real mystery. Let's look at all sides of it. There's Perry. There's Morley. And—there's Miss Maria Fulton."

"Miss Fulton!"

"Yes—a possibility."

"Oh, I don't connect her up with it any." The chief's voice was tinged with ridicule.

Bristow answered a knock on the door and opened to admit a uniformed policeman.

"Beg your pardon, chief," said the officer, "but I had something for a Mr. Morley. The men on guard down there at Number Five wouldn't let me in to see him—said I'd better see you."

"What have you got, Avery?" asked Greenleaf.
