Recently graduated and now a junior astrogator, Ben Carson punches an irritating drunkard in Luna City, killing him with one punch. Fleeing the scene, he heads to Venus. There was just one flaw in his decision. He hadn't realized that the memory of the dead man's face would haunt him, torment him, follow him as constantly as breath flowed into his lungs. But might not the rumble of atomic engines drown the murmuring dead voice? Might not the vision of alien worlds and infinite spaceways obscure the dead face? Arriving on Venus, he joins an underground movement in exchange for their help. Unfortunately, his tortured conscience prevents his wholehearted commitment to their cause.
