Shano coughed, wracking his body, as forgotten memories stirred sluggishly in his mind. "Yup," he said, and jerked free and stumbled down the steel deck. In his cabin he lay on the bunk, lighted a cigarette and smoked, coughing and staring at the rivet-studded bulkhead. The slow movement of his mind resolved into a struggle, one idea groping for the other. What were the things he'd heard about nicked jaws? And where had he heard them? Digging ore on Pluto; talk in the pits? Secretive suspicions voiced in smoke-laden saloons of Mars? In the labor gangs of Uranus? Where? Shano smoked and didn't know.

Shano followed him; followed the bluish glow of his bulb, through labyrinthine passages and down a companionway, coughing and leering against the pain in his joints. The blue light winked out in the distance and Shano stopped. He was suddenly alarmed. The captain had
