"Has the gentleman lived here long?"

"Only took the rooms yesterday. Hasn't moved in yet."

Evan's heart went down. "Oh, then he isn't in?"

"Yes, he and his friend are up there waiting for the furniture."

She was evidently a victim rather than an accomplice. Still no sign of the police! George Deaves had not the assurance to keep up his pretended search. Evan signalled to him with a look to hand over the envelope. He did so with trembling hands.

At the same moment Evan, whose ears were stretched for sounds from within the house, heard a voice say, not loud: "They're coming over the back fence!" And another voice answered: "Beat it, then."

To Evan it was like the view halloo of the huntsman. He could not resist it. Never thinking of danger, he pushed past the astonished landlady and sprang for the stairs, pulling his pistol as he ran. As he left the stoop he had an impression of a motor van turning the corner from MacDougall.

The woman screamed, and George Deaves yelled to Evan to come back. The woman slammed the door in Deaves' face with the impulse of keeping out at least one intruder. This was unfortunate for Evan, for it delayed the entrance of the police.

As Evan went up the first flight he heard flying feet on the stairs overhead, and he made no pause on the second floor. He heard a door on the third floor slam. It was in the front. Houses of this type have a window on the stair landing and Evan had no difficulty in seeing what he was about.

On the third floor there were four doors on the hall, all closed. Evan went directly to the door he had heard close, the door of the principal front room, and throwing it open, stepped back, half expecting a fusillade from within. But none came. After a moment he stepped to the door and looked in. The room was empty. But there was a door communicating with the rear.
