I was standing by a high wall of foliage, close to the lakeside and had just started to light a cigarette. All at once, directly overhead, there was a rustling sound that was hard to mistake, for I'd heard it many times before, and it had a peculiar quality which set it apart from all other sounds.

Something was moving through the shadows above me, rustling dry leaves, slithering down toward me with a dull, mechanical buzzing.

The buzzing stopped abruptly and there was a flash of brightness, a long-drawn whining sound. I braced myself, letting my arms swing loosely at my side.

With startling swiftness something long, glistening and snakelike descended upon me and wrapped itself around my right leg just above the knee. Before I could shake it loose it contracted into a tight knot and the whining turned into a shrill scream, prolonged, ghastly. It was quite unlike the scream of an animal. There was something metallic, rasping about it, as if more than animal ferocity was giving voice to its pent-up rage in a shrill mechanical monotone.

The constriction increased and an agonizing stab of pain lanced up my thigh. I raised my right arm and brought the edge of my hand down with an abrupt, chopping motion. I chopped downward three times, not at random, but with a calculated, deadly precision, for I knew that a misdirected blow could have cost me my life.

I was in danger only for an instant, and not a very long instant at that. The damage I'd done to it caused it to release its grip on my leg, shudder convulsively and drop to the ground.

Damaged where it was most vulnerable, it writhed along the ground with groping, disjointed movements of its entire body. Tiny fragments of shattered crystal glistened in its wake, and two long wires dangled from its cone-shaped head.

Its segmented body-case glowed with a blood-red sheen as it writhed across a flat gray stone on the edge of the lakeshore embankment, and reared up for an instant like an enormous, sightlessly groping worm. Then, abruptly, all the animation went out of it, and it flattened out and lay still. Both of the optical disks which had enabled it to move swiftly through the darkness had been smashed. I was no longer in any danger and it was very pleasant just to know that.

Very pleasant indeed.

An attempt had been made on my life. There could be no blinking the fact. That little mechanical horror, with its complex interior mechanisms, had been set upon me from a distance with all of its electronic circuits clicking by remote control.
