In either case, he always insisted that the piece be tested. He refused either to buy or sell something that didn't work. So you'd follow him down that long hallway to the lab in the rear, where all the testing equipment was. The lab, too, was cluttered, but in a different way. Out front, the stuff was dead; back here, there was power coursing through the ionic veins and metallic nerves of the half-living machines. Things were labeled in neat, accurate script--not for Old Harry's benefit, but for the edification of his customers, so they wouldn't put their fingers in the wrong places. He never had to worry about whether his customers knew enough to fend for themselves; a few minutes spent in talking was enough to tell Harry whether a man knew enough about the science and art of electronics and sub-electronics to be trusted in the lab. If you didn't measure up, you didn't get invited to the lab, even to watch a test. But he had very few people like that; nobody came into Harry MacDougal's place unless he was pretty sure of what he wanted and how he wanted to use it. On the other hand, there were very few men whom Harry would allow into the lab unescorted. Mike the Angel was one of them. Meet Mike the Angel. Full name: Michael Raphael Gabriel. (His mother had tagged that on him at the time of his baptism, which had made his father wince in anticipated compassion, but there had been nothing for him to say--not in the middle of the ceremony.) Naturally, he had been tagged "Mike the Angel." Six feet seven. Two hundred sixty pounds. Thirty-four years of age. Hair: golden yellow. Eyes: deep blue. Cash value of holdings: well into eight figures. Credit: almost unlimited. Marital status: highly eligible, if the right woman could tackle him. Mike the Angel pushed open the door to Harry MacDougal's shop and took off his hat to brush the raindrops from it. Farther uptown, the streets were covered with clear plastic roofing, but that kind of comfort stopped at Fifty-third Street. There was no one in sight in the long, narrow store, so Mike the Angel looked up at the ceiling, where he knew the eye was hidden. "Harry?" he said. "I see you, lad," said a voice from the air. "You got here just in time. I'm closin' up. Lock the door, would ye?" "Sure, Harry." Mike turned around, pressed the locking switch, and heard it snap satisfactorily. "Okay, Mike," said Harry MacDougal's voice. "Come on back. I hope ye brought that bottle of scotch I asked for." Mike the Angel made his way back between the towering tiers of bins as he answered. "Sure did, Harry. When did I ever forget you?" And, as he moved toward the rear of the store, Mike the Angel casually reached into his coat pocket and triggered the switch of a small but fantastically powerful mechanism that he always carried when he walked the streets of New York at night. He was headed straight into trouble, and he knew it. And he hoped he was ready for it. 2
