have another session with the computer after his conference with FitzMaugham and Ludwig. Perhaps it still wasn't too late to erase the damning data and cover his mistake. Then it would be just his word against Fred's. He might yet be able to brazen through, he thought dully. He ordered lunch with quivering fingers, and munched drearily on the tasteless synthetics for awhile before dumping them down the disposal chute. IV At precisely 1255 Walton tidied his desk, rose and for the second time that day, left his office. He was apprehensive, but not unduly so; behind his immediate surface fears and tensions lay a calm certainty that FitzMaugham ultimately would stick by him. And there was little to fear from Fred, he realized now. It was next to impossible for a mere lower-level medic to gain the ear of the director himself; in the normal course of events, if Fred attempted to contact FitzMaugham, he would automatically be referred to Roy. No; the danger in Fred's knowledge was potential, not actual, and there might still be time to come to terms with him. It was almost with a jaunty step that Walton left his office, made his way through the busy outer office, and emerged in the outside corridor. Fred was waiting there. He was wearing his white medic's smock, stained yellow and red by reagents and coagulants. He was lounging against the curving plastine corridor wall, hands jammed deep into his pockets. His thick-featured, broad face wore an expression of elaborate casualness. "Hello, Roy. Fancy finding you here!" "How did you know I'd be coming this way?" "I called your office. They told me you were on your way to the lift tubes. Why so jumpy, brother? Have a tough morning?" "I've had worse," Walton said. He was tense, guarded. He pushed the stud beckoning the lift tube. "Where you off to?" Fred asked. "Confidential. Top-level powwow with Fitz, if you have to know." Fred's eyes narrowed. "Strictly upper-echelon, aren't you? Do you have a minute to talk to a mere mortal?"
