in this that must be avoided. That afternoon he had noticed there was a telephone in the house. He now walked back to a drug store on whose front he had seen the sign of a public telephone. He closed himself in the booth, and soon had Lillian Drew on the wire. "This is a friend with a tip," he said. "I just happened to overhear a man ask a policeman to come with him to arrest you." "What was the man like?" came tremulously from the receiver. David began a faithful description of himself, but before he was half through he heard the receiver at the other end of the wire click into place upon its hook. He returned to where he had a view of the entrance of the apartment house, and almost at once he saw Lillian Drew come hurriedly out. He then walked over to Broadway, asked a policeman to arrest a woman on his complaint, and led the officer to the apartment house.

He wandered about, passing the house from time to time. Toward twelve o'clock, when he again drew near the house, the great van of a storage warehouse was before it, and men were carrying out furniture. Beside the van stood an express wagon in which was a trunk, and coming out of the doorway was a man bearing on his back another trunk, from the end of which dangled a baggage check. As the man staggered across the sidewalk, David stepped behind him, caught the tag and read it
