"Probably the Doctor," murmured Miss Cornelia uncertainly as the doorbell rang again. "He was to come back with some sleeping-powders."
Billy appeared for the key of the front door.
"If that's Doctor Wells," warned the detective, "admit him. If it's anybody else, call me."
Billy grinned acquiescently and departed. The detective moved nearer to Bailey.
"Have you got a gun on you?"
"No." Bailey bowed his head.
"Well, I'll just make sure of that." The detective's hands ran swiftly and expertly over Bailey's form, through his pockets, probing for concealed weapons. Then, slowly drawing a pair of handcuffs from his pocket, he prepared to put them on Bailey's wrists.
