door 
that looked as though it might conceal a closet. 
It didn't. It was the door to a veddy, veddy expensive apartment with 
equally expensive appointments. One wall, thirty feet long and ten feet 
high, was a nearly invisible, dustproof slab of polished, optically flat 
glass that gave the observer the feeling that there was nothing between 
him and the city street, five hundred feet below. 
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. 
The phone chimed. 
Mike went over to it, punched the switch, and said: "Gabriel speaking." 
No image formed on the screen. A voice said: "Sorry, wrong number." 
There was a slight click, and the phone went dead. Mike shrugged and 
punched the cutoff. Sounded like a woman. He vaguely wished he 
could have seen her face. 
Mike got up and walked back to his easy chair. He had no sooner sat 
down than the phone chimed again. Damn! 
Up again. Back to the phone. 
"Gabriel speaking." 
Again, no image formed. 
"Look, lady," Mike said, "why don't you look up the number you want 
instead of bothering me?" 
Suddenly there was an image. It was the face of an elderly man with a 
mild, reddish face, white hair, and a cold look in his pale blue eyes. It 
was Basil Wallingford, the Minister for Spatial Affairs. 
He said: "Mike, I wasn't aware that your position was such that you 
could afford to be rude to a Portfolio of the Earth Government." His 
voice was flat, without either anger or humor. 
"I'm not sure it is, myself," admitted Mike the Angel, "but I do the best 
I can with the tools I have to work with. I didn't know it was you, 
Wally. I just had some wrong-number trouble. Sorry."
"Mf.... Well.... I called to tell you that the Branchell is ready for your 
final inspection. Or will be, that is, in a week."
