Captain Davidson Greer sat in the gun tower that overlooked the Officers' Barracks and the courtyard surrounding the five-story building. He was a tall, solidly built man in his early thirties, with dark gray-green eyes and dark blond hair. He didn't particularly care for gun-tower duty, but this sort of thing couldn't be left to anyone who was not in on the secret of the Nipe. As long as Colonel Mannheim was here in Government City, there would be special officers guarding him instead of the usual guard contingent.
Not that Captain Greer was actually expecting the Nipe to make any attempt on the colonel's life; that was too remote to be worried about. But the gun towers had been erected fifty or more years before because there were always those who wanted to attempt assassination. Officers of the World Police had not enjoyed great popularity during the reconstruction period after the Holocaust. The petty potentates who had set themselves up as autocratic rulers in various spots over the Earth had quite often decided that the best way to get the WP off their backs was to kill someone, and quite often that someone was a Police officer. Disgruntled nationalists and fanatics of all kinds had tried at various times to kill one officer or another. The protection was needed then.
Even now there were occasional assassins who attempted to invade World Police Headquarters, but they were usually stopped long before they got into the enclosure itself.
Still, there was always the chance. There had been, in the past few years, an undercurrent of rebellion all over Earth because of the Nipe. The monster hadn't been killed, and there were those who screamed that the failure was due to the inefficiency of the Police.
One attempt had already been made on the life of a Major Thorensen because he had failed to get the Nipe after a raid in Leopoldville. The would-be assassin had been cut down just before he threw a grenade that would have killed half a dozen men. Captain Greer had been assigned to make sure that no such attempt would succeed with Colonel Mannheim.
He could see the length of the hallway that led to Colonel Mannheim's suite. The hallway had been purposely designed for watching from the gun tower. To one who was inside, it looked like an ordinary hallway, stretching down the length of the building. But it was walled with a special plastic that, while opaque to visible light, was perfectly transparent to infra-red. To the ordinary unaided eye, the walls of the building presented a blank face to the gun tower, but to the eye of an infra-red scope, the hallways of all five floors looked as though they were long, glass-enclosed terraces. And those walls were neither the ferro-concrete of the main building nor the pressure glass of the windows, but ordinary heavy-gauge plastic. To the bullets that could be spewed forth from the muzzle of the heavy-caliber, high-powered machine gun in the tower, those walls were practically nonexistent.
Captain Greer surveyed the hallways with his infra-red binoculars. Nothing. The halls were empty. He lowered the binoculars and lit a cigarette. Then he put his eyes to the aiming scope of the gun and swiveled the muzzle a little. The aiming scope showed nothing either.
He leaned back and exhaled a cloud of smoke.
