But, after all, what did Brittain matter? According to the records, he was born Alex Bretinov, in Marseilles, France, in nineteen sixty-eight. His father, a dyed-in-the-wool Old Guard Communist, had been born in Minsk in nineteen forty. _Or had he been wound up, and his clockwork started in January of nineteen fifty-three?_ The radio popped. "Eighteen. Alert. Brittain just left his place on foot. Carson, Reymann following. Over." Lansberg dropped his magazine. "He seems to be heading for the Big Boy--I hope." The ground car followed him to a subway, and two men on foot followed him in from Flatbush Avenue. * * * * * Some hours later, after much devious turning, dodging, and switching, Brittain climbed into a taxi on the corner of Park Avenue and Forty-seventh Street, evidently feeling he had ditched any tails he might have had. Karnes and Lansberg were right behind him in a radio car. The cab headed due south on Park Avenue, following it until it became Fourth, swung right at Tenth Street, past Grace Church, across Broadway. At Sixth, it angled left toward Greenwich Village. "Somewhere in the Village, nickels to knotholes," Lansberg guessed as he turned to follow. Karnes, at the radio, was giving rapid-fire directions over the scrambler-equipped transceiver. By this time, several carloads of agents and police were converging on the cab from every direction. From high above, could be heard the faint hum of 'copters. Lansberg was exultant. "We've got them for once! And the goods on every essobee in the place." The cars hummed smoothly through the broad streets, past the shabby-genteel apartment neighborhood. Back in the early sixties, some of these buildings had been high-priced hotels, but the Village had gone to pot since the seventies. A few minutes later, the cab pulled up in front of an imposing looking building of slightly tarnished aluminum paneling. Brittain got out, paid his fare, and went inside. As the cab pulled away, Karnes gave orders for it to be picked up a few blocks away, just in case. The rest of the vehicles began to surround the building. Karnes, meanwhile, followed Brittain into the foyer of the apartment hotel. It was almost a mistake. Brittain hadn't gone in. Evidently attracted by the footsteps following him, he turned and looked back out. Karnes wasn't more than ten feet away. _Just pretend you live here_, thought Karnes, _and bully-boy will never know the difference_. He walked right on up to the doorway, pretending not to notice Brittain. Evidently, the saboteur was a little flustered, not quite knowing who Karnes was. He, too, pretended that he had no suspicions. He pressed a buzzer on the panel to announce himself to a guest. Karnes noticed it was 523; a fifth floor button. The front door, inside the foyer, was one of those gadgets with an electric lock that doesn't open unless you either have a key to the building or can get a friend who lives there to let you in.
