there was enough in the pay envelope to buy what he needed—a flash camera, a little folding shovel from one of the surplus houses, and a bottle of good scotch. It would be dark enough for him to taxi out to Oakhaven Cemetery, where Blanding had been buried.

It wouldn't change the minds of the fools, of course. Even if he could drag back what he might find, without the change being completed, they wouldn't accept the evidence. He'd been crazy to think anything could change their minds. And they called him a fanatic! If the facts he'd dug up in ten years of hunting wouldn't convince them, nothing would. And yet he had to see for himself, before it was too late!

He picked a cheap hotel at random and checked in under an assumed name. He couldn't go back to his room while there was a chance that Jordan still might try to turn him in. There wouldn't be time for Sylvia's detectives to bother him, probably, but there was the ever-present danger that one of the aliens might intercept the message.

He shivered. He'd been risking that for ten years, yet the likelihood was still a horror to him. The uncertainty made it harder to take than any human-devised torture could be. There was no way of guessing what an alien might do to anyone who discovered that all men were not human—that some were ... zombies.

There was the classic syllogism: All men are mortal; I am a man; therefore, I am mortal. But not Blanding—or Corporal Harding.

It was Harding's "death" that had started it all during the fighting on Guadalcanal. A grenade had come flying into the foxhole where Dane and Harding had felt reasonably safe. The concussion had knocked Dane out, possibly saving his life when the enemy thought he was dead. He'd come to in the daylight to see Harding lying there, mangled and twisted, with his throat torn. There was blood on Dane's uniform, obviously spattered from the dead man. It hadn't been a mistake or delusion; Harding had been dead.

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
