light. What a filthy trick! Mooney all but sobbed to himself. He picked up the squarish thing bitterly. Probably it wouldn't even work, he thought, the world a ruin around him. It wasn't even the whole complete weapon. Still— There was a grooved, saddle-shaped affair that was clearly a sort of trigger; it could move forward or it could move back. Mooney thought deeply for a while. Then he sat up, held the thing carefully away from him with the pointed part toward the wall and pressed, ever so gently pressed forward on the saddle-shaped thumb-trigger. The pale blue haze leaped out, swirled around and, not finding anything alive in its range, dwindled and died. Aha, thought Mooney, not everything is lost yet! Surely a bright young man could find some use for a weapon like this which removed, if it did not kill, which prevented any nastiness about a corpse turning up, or a messy job of disposal. Why not see what happened if the thumb-piece was moved backward? Well, why not? Mooney held the thing away from him, hesitated, and slid it back. There was a sudden shivering tingle in his thumb, in the gadget he was holding, running all up and down his arm. A violet haze, very unlike the blue one, licked soundlessly forth—not burning, but destroying as surely as flame ever destroyed; for where the haze touched the gadget itself, the kit, everything that had to do with the man from the future, it seared and shattered. The gadget fell into white crystalline powder in Mooney's hand and the case itself became a rectangular shape traced in white powder ridges on the rug.

What he saw, he didn't believe; what he believed filled him with panic. No wonder Harse had laughed so when Mooney asked if its victims were dead. For there they were, all of them. Like djinn out of a
