The First Man on the Moon by Alfred Coppel - John Thurmon swore he'd be the first man on the moon. But he wasn't. He was only the first murderer.

The ship lay at a crazy angle on the stark whiteness of the pumice plain. The rocket nozzles were a fused lump of slag; the fire-darkened hull crumpled and warped by the impact of landing. And there was silence ... complete and utter silence.

There could be no return. Thurmon realized this. At first the thought had brought panic, but, as the scope of his achievement dawned on him, the fear retreated. Bruised, giddy, half-crazed ... the certainty of death held no terrors. Not yet. And it was worth it! Fame ... immortality! Glory ... in return for the last few years of a blighted, embittered, over-shadowed life. Yes, it was well worth it. And, except for the crash-landing and the certainty of no return, it had all come to pass just as he had planned it for so long.

On his knees he caressed the gritty soil. He lifted his arms toward the Day Star flaming in the day-night of space and knew completion. Tears streaked his stubbled face, and strange noises came from his slack mouth. The ecstasy of success was almost unbearable. For this, he had labored a lifetime. For this, he had murdered a friend....

Across the abyss, the whole world waited for word. The transmitter in the rocket had survived the crash. The word would come, thought Thurmon ... when he was ready to send it. And sending it, he would place the official seal of immortality on his brow. The book would close. But wonderfully, satisfyingly. There would be no other to steal his rightful glory. Only Wayne could have done that ... and Wayne was dead. He laughed weirdly within his helmet. So simply done!
