Trans-U Miners Union housed itself in a citadel remarkable even on Mars. It occupied the center of a large area, cleared, floodlighted and surrounded by a charged wire fence. Inside the defense circle were booby traps triggered for the first careless step off marked pathways patrolled by robot guards. Torry's metal ident card got him through the gateway by tripping electronic relays, and each incorruptible robot guard passed him after being shown the card. At the building doorway he had to satisfy a series of dubious and hard bitten human questioners, but his pass and the magic name of Ferax got him inside. Doors opened. Robot voices directed him across echoing lobbies to a bank of elevators. In a locked cage he descended five floors below surface level. In the corridor another bodiless voice spoke: "End of the hall. Door on the right." Torry followed directions. The ritual was getting on his nerves. His footsteps echoed hollowly. The place smelled damp and moldy as a tomb. Opening the door on the right with a wave of his keyed pass, he realized that it was, in a sense, a tomb. There was a body in it. A dead body. Ferax sprawled across an ornate desk of Venusian chibar wood and kru-leather. Luminous particles from a blaster discharge still danced in the air. A lingering bite of charred, exploding flesh stung the nostrils. There was little left of the torso, but a lolling globular head identified the corpse. A discarded gun clanked as Torry's foot kicked it. He hesitated, then picked it up and renewed the charge. It was an automatic reflex of defense, and fingerprint evidence was not likely to matter now. If found on the spot he would have little chance for explanations. The thing had happened only minutes ago. Whoever did it, the killer must still be close at hand. A roving flicker of pale radiance warned Torry that a scanner was in use. By whom? From where? No complex mental processes were needed to convince Torry that he was in a bad spot. The goon squads were notorious for acting first and asking questions afterwards. Getting into the citadel to see Ferax had been interesting enough. Getting out again promised to be more so. If he ever got out. The office door was opening slowly. Silently Torry glided behind it. Reaching around it, he snatched cloth and flesh and dragged a struggling form into the room.
