"There's a mistake, you blamed ass!" he screamed. "I ain't one of 'em! Alden! Martin!"

A hand was pressed firmly over his mouth, and with veins swelling up and eyes starting from his head in impotent fury, Mr. Oppner was hustled forward through the darkness.

Around him a number of people seemed to be moving, and when he found his feet upon stairs, several unseen hands were outstretched to thrust him upward. The darkness was impenetrable.

Apparently the stair was uncarpeted, as likewise was the corridor along which he presently found himself proceeding. The echo of many footsteps rang through the house. It sounded shell-like, empty. Then it seemed to him that not so many were about him. He felt his revolver slide from his hip-pocket. He was pushed gently forward, and a door closed behind him. The sound of footsteps died away with that of whispering voices.

Came a sudden angry roar, muffled, distant, he thought in the voice of Alden. It was stifled, cut off ere it had come to full crescendo, in a very significant manner. Silence, then, fell about him, the chill silence of an empty house.

Cautiously he turned and felt for the door, which he knew to be close behind him. He was obsessed by a childish, though not unnatural, fear of falling through some trap.

He touched the door-knob, turned it. As he had anticipated, the door was locked. He wondered if there were any windows to this strangely dark apartment. With his fingers touching the wall, he crept slowly forward, halting at every other step to listen; but the night gave up no sound.

The tenth pace brought him to a corner. He turned off at right angles, still pursuing the wall, and came upon shutters, closely barred. He pressed on, came to another corner; proceeded, another; and finally touched the door-knob again.

This was a square room, apparently, and unfurnished. But what might not yawn for him in the middle of the floor? He remembered that the river ran at the end of the garden.

Pressing his ear to the door, he listened intently.
