It had taken Dane two days of crawling and hiding to get back to his group, too exhausted to report Harding's death. He'd slept for twenty hours. And when he awoke, Harding had been standing beside him, with a whole throat and a fresh uniform, grinning and kidding him for running off and leaving a stunned friend behind. It was no ringer, but Harding himself, complete to the smallest personal memories and personality traits. * * * * * The pressures of war probably saved Dane's sanity while he learned to face the facts. All men are mortal; Harding is not mortal; therefore, Harding is not a man! Nor was Harding alone--Dane found enough evidence to know there were others. The _Tribune_ morgue yielded even more data. A man had faced seven firing squads and walked away. Another survived over a dozen attacks by professional killers. Fingerprints turned up mysteriously "copied" from those of men long dead. Some of the aliens seemed to heal almost instantly; others took days. Some operated completely alone; some seemed to have joined with others. But they were legion. Lack of a clearer pattern of attack made him consider the possibility of human mutation, but such tissue was too wildly different, and the invasion had begun long before atomics or X-rays. He gave up trying to understand their alien motivations. It was enough that they existed in secret, slowly growing in numbers while mankind was unaware of them. When his proof was complete and irrefutable, he took it to his editor--to be fired, politely but coldly. Other editors were less polite. But he went on doggedly trying and failing. What else could he do? Somehow, he had to find the few people who could recognize facts and warn them. The aliens would get him, of course, when the story broke, but a warned humanity could cope with them. _Ye shall know the truth, and the truth shall make you free._ Then he met Sylvia by accident after losing his fifth job--a girl who had inherited a fortune big enough to spread his message in paid ads across the country. They were married before he found she was hard-headed about her money. She demanded a full explanation for every cent beyond his allowance. In the end, she got the explanation. And while he was trying to cash the check she gave him, she visited Dr. Buehl, to come back with a squad of quiet, refined strong-arm boys who made sure Dane reached Buehl's "rest home" safely. Hydrotherapy ... Buehl as the kindly firm father image ... analysis ... hypnosis that stripped every secret from him, including his worst childhood nightmare. His father had committed a violent, bloody suicide after one of the many quarrels with Dane's mother. Dane had found the body. [Illustration]
