Soft come the dragons

the mutant felt justified in leaving the scene long enough to notify the police. But then, someone screamed.
    It was a woman's scream, high and piercing. It started full strength, turned to a gurgle much like Taguster's, and trailed away. It had come from the direction of the bedroom. There was another receiver in there, an extension of the living room box, and Ti vacated his present perch for the bedroom set.
    It was a woman. She had been trying to get out of the window, but her flimsy nightdress had caught on the window latch, delaying her just a moment too long. There were three darts in her back, and the yellow negligee was running with red, red blood. Ti looked to the right, hunting the killer. He had assumed the man had left, but he had only disabled Taguster, then had gone quickly on to the woman to kill her before she could escape. The blood had now soaked her negligee and was dripping onto the floor from the frilly lace edging. He shifted the camera to the left, and he saw his killer. And it wasn't a man . . .
    It was a Police Hound. Its dark metal body floated toward the doorway, its two servo-hands flying ahead of it, their fingers tensed as if they were ready to latch onto something and strangle it to death. The dart tube on its burnished belly was protruding, prepared for action. This was the killer, thirty-odd pounds of ball-shaped computer that could track a man by smell, sight, touch, and sound. And only the police should have one!
    But why would the police want to kill Leonard Taguster? And why should they use such a roundabout method of obtaining his destruction? Why not simply haul him in on some phony charge replete with carefully prepared evidence and do away with him legally?
    The Hound disappeared through the doorway into the hall, and Ti suddenly remembered Taguster lying back there in the living room. The Hound was going back to finish the job! The darts were evidently tipped with poison, though Police Hounds should carry only defense-and-capture narcotics. Now that Taguster's lover had been kept from spreading the news, it was time to take care of the guitarist in proper fashion.
    Ti retreated from the bedroom connection and shifted his mind back to the main receiver. Taguster was still lying against the wall in the same position, still not unconscious, still gurgling, trying to tell Ti who Margie was. But the Hound was on its way! Ti searched the room frantically for a weapon.
    The Hound came through the doorway and drifted toward Taguster.
    Ti found a curio, a small brass peasant leading a small brass mule, a hand-crafted trinket Taguster had brought back from his tour of Mexico. He lifted it with his psi power and threw it at the Hound. The toy bounced off the dully gleaming hide of the machine, fell harmlessly to the floor. The Hound drifted at Taguster, its dart tube thrusting farther out of its underside, its servos spreading to either side to give it a clear line of fire.
    Ti found an ashtray, tried lifting it, could not.
    Panic threatened to tip him into irrationality. But that, he cautioned himself, would do the musician no good at all. He was the man's only hope! There were only seconds left. Then he remembered the gun on the desktop. It had been lying at the opposite end from the pencils, heavy and ugly, a deterrent to burglars. He touched the pistol psionically, but he could not nudge it. He pressed harder, eventually moved it slightly until the barrel was pointing toward the Hound. Pulling the light wire of the automatic trigger was easy. The gun spat a narco-needle that bounced off the beast. That was no good!
    And then the Hound shot Taguster. Four times in the chest: thud, thud, thud, thud! The guitarist gurgled thickly, sighed, and dropped his head, quite dead now. Ti felt as if all the energy he had possessed had been sucked out of him by an electric vampire, yet he could not let the Hound escape. He sent his cameras swiveling about, looking for things small enough to be handled by his limited talents. He found various trinkets and figurines and rained them uselessly upon the killer machine. It surveyed the room, perplexed, firing darts in the direction from which the souvenir hail came, unable to discover its assailant. Then it turned a spatter of darts on the receiver head and floated out of the room—out of the house and away . . .
    For a time, Ti remained in the living room receiver, looking at Taguster's corpse. He was too weakened to do anything else. His mind filled
