Intent on their work of breaking in the door, the policemen paid little attention to their audience, and apparently did not notice that the door across the hall was still closed and silent. Murphy, however, recalled this fact later on.

At last, with a crash and a splintering of wood, the lock gave way and the door flew open. All was darkness and silence before them.

The five men stood grouped in the doorway, listening intently. The black silence remained unbroken save for the labored breathing of the men who had just broken in the door. The plain-clothes man then brought forth an electric pocket lamp and flashed its rays into the entrance hall, while the others drew their revolvers and held them in readiness. Then all stepped into the hallway. This was a large, square entrance way with four doorways opening from it. Two closed doors faced them. As they discovered later, these led to a bedroom, and the bathroom. The others, one opening toward the front of the apartment, and one toward the rear, were wide archways covered with heavy velvet portieres.

The plain-clothes man found the wall switch and turned on the electric light. Instructing one of his companions to watch the hall door, he led the others in a search of the apartment. Seeking for the electric light buttons as they moved about the apartment, the men soon flooded the rooms with light. Each man with revolver ready, and intent on searching every corner, none of them gave much attention to the fact that Marsh was dogging every move, apparently as keenly on the lookout as any one of the party.

Their inspection revealed nothing more than that the apartment was apparently in the same condition as its tenant had left it. The door to the outside stairway at the back was locked and the key was missing. In addition to the regular lock a stout bolt was in place. The catches on all the windows were properly locked, and all the shades remained drawn down close to the sills. It was an empty, locked apartment, with no outstanding evidence of having been used for a long time.

The police, now joined by the man lately on watch at the door, stood nonplussed in the kitchen. The plain-clothes man uttered an oath. Then he addressed his companions.

"I've seen some mighty fishy situations, but this trims anything I ever ran up against. Ain't been just hearing things, have you, Murphy? A swig of this home-made hootch does upset a man dreadful, sometimes."

Murphy glared.

"I ain't never touched the stuff," he bellowed. Then added, aggressively, "You know damned well I wasn't the only one to hear that shot. The tenant downstairs heard it, too. It was him that brought me in."

"Well, you only got his word for it that this is where the shot, was fired. Maybe HE'S trying to cover something up."
