darkness befriended Dave. In the massed mêlée they dared not shoot for fear of hitting the wrong mark. Nor could they always be sure which shifting figure was the enemy.

Dave clung close to the man he had seized, using him as a shield against the others. The pack swayed down the hall into the wedge of light thrown by the lamp in the room.

Across the head of the man next him Shorty reached and raised his arm. Dave saw the blue barrel of the revolver sweeping down, but could not free a hand to protect himself. A jagged pain shot through his head. The power went out of his legs. He sagged at the hinges of his knees. He stumbled and went down. Heavy boots kicked at him where he lay. It seemed to him that bolts of lightning were zigzagging through him.

The pain ceased and he floated away into a sea of space.
