The lights of the city, coming through the wall, gave the room plenty of illumination after sunset, but the simple flick of a switch could polarize it black, allowing perfect privacy.
The furniture was massive, heavily braced, and well upholstered. It had to be; Mike the Angel liked to flop into chairs, and his two hundred and sixty pounds gave chairs a lot of punishment.
On one of the opaque walls was Dali’s original “Eucharist,” with its muffled, robed figures looking oddly luminous in the queer combination of city lights and interior illumination. Farther back, a Valois gleamed metallically above the shadowed bas-reliefs of its depths.
It was the kind of apartment Mike the Angel liked. He could sleep, if necessary, on a park bench or in a trench, but he didn’t see any reason for doing so if he could sleep on a five-hundred-dollar floater.
As he had passed through each door, he had checked them carefully. His electrokey had a special circuit that lighted up a tiny glow lamp in the key handle if the lock had been tampered with. None of them had.
He opened the final door, went into his apartment, and locked the door behind him, as he had locked the others. Then he turned on the lights, peeled off his raincoat, and plopped himself into a chair to unwrap the microcryotron stack he had picked up at Harry’s.
Theoretically, Harry wasn’t supposed to sell the things. They were still difficult to make, and they were supposed to be used only by persons who were authorized to build robot brains, since that’s what the stack was—a part of a robot brain. Mike could have put his hands on one legally, provided he’d wanted to wait for six or eight months to clear up the red tape. Actually, the big robotics companies didn’t want amateurs fooling around with robots; they’d much rather build the robots themselves and rent them out. They couldn’t make do-it-yourself projects impossible, but they could make them difficult.
In a way, there was some good done. So far, the JD’s hadn’t gone into big-scale robotics. Self-controlled bombs could be rather nasty.
Adult criminals, of course, already had them. But an adult criminal who had the money to invest in robotic components, or went to the trouble to steal them, had something more lucrative in mind than street fights or robbing barrooms. To crack a bank, for instance, took a cleverly constructed, well-designed robot and plenty of ingenuity on the part of the operator.
Mike the Angel didn’t want to make bombs or automatic bankrobbers; he just wanted to fiddle with the stack, see what it would do. He turned it over in his hands a couple of times, then shrugged, got up, went over to his closet, and put the thing away. There wasn’t anything he could do with it until he’d bought a cryostat—a liquid helium refrigerator. A cryotron functions only at temperatures near absolute zero.
