man be stabbed without feeling any pain at all? He didn't know. But at least his shoulder wasn't paralyzed. He could move his arm freely, flex the muscles of his back. How unbelievably cruel it was that a ship could move through space with the stability of a completely stationary object. How unbelievably cruel at this moment, when the slightest lurch might have saved him. The girder was stationary and immense, and in his tormented inward vision he saw it as a strand in a gigantic steel cobweb, symbolizing the grandeur of what man could accomplish by routine compulsion alone. In frozen helplessness Corriston tried to bring his thoughts into closer accord with reality, to view his peril in a saner light. But what was happening to him was as hard to relate to immediate reality as a line half remembered from a play. See how the blood of Caesar followed it, as if rushing out of doors to be resolved if Brutus so unkindly knocked or no.... But the killer wasn't Brutus. He was unknown and invisible and if there had been any Brutuslike nobility in him, it hardly seemed likely that he would have chosen for his first victim a wealthy girl's too talkative bodyguard and for his second Corriston himself. The killer was within arm's reach again when the barrier that had trapped Corriston fell away abruptly. He reeled back, swayed dizzily, and experienced such wild elation that he cried out in unreasoning triumph. Swiftly he retreated backwards, not fully realizing that no real respite had been granted him. He was free only to recoil a few steps, to crouch and weave about. Almost instantly the killer was closing in again, and this time there was no escape. Another metal girder stopped Corriston in midretreat, cutting across his shoulders like a sharp-angled priming rod, jolting and sobering him. For an eternity now he could do nothing but wait. An eternity as brief as a dropped heartbeat and as long as the cycle of renewal and rebirth of worlds in the flaming vastness of space. Everything became impersonal suddenly: the darkness of the ships' between-deck storage compartment; the Space Station toward which the ship was traveling; the Martian deserts he had dreamed about as a boy. The killer spoke then, for the first time. His voice rang out in the darkness, harsh with contempt and rage. It was in some respects a surprising voice, the voice of an educated man. But it was also a voice that had in it an accent that Corriston had heard before
