came back, and nearly always accompanied by profanity and threats. Charley was spectacular, and a monstrous care but Denver ended by becoming fond of the nuisance. He would miss the radiant, stupid and embarrassingly affectionate creature. Charley had currently burned out a transformer by some careless and exuberant antic; hence the mutual doghouse. Scolding was wasted effort, so Denver merely sighed and made a face at Charley. "Mad dogs and Martians go out in the Lunar sun," he sang as a punishment. Charley recognized only the word "dog" but he considered the song a personal insult; as if Denver's singing were not sufficient punishment for a minor offense. Charley was irritated. Charley's iridescence flickered evilly, which was enough to short-circuit two relays and weld an undetermined number of hot switches. Charley's temper was short, and short-circuiting all electrical units within range was mere reflex. Tod Denver swore nobly and fluently, set the controls on automatic-neutral and tried to localize the damage. But for Charley and his overloaded peeve, they would have been in Crystal City inside the hour. So it was Charley's fault, of course; all of it.... t was beyond mere prank. Denver calculated grimly that his isolated suit would hold up less than twenty minutes in that noon inferno outside before the stats fused and the suiting melted and ran off him in droplets of metal foil and glass cloth. The thermal adjustors were already working at capacity, transmitting the light and heat that filtered through the mirror-tone hull into stored, useful energy. Batteries were already overcharged and the voltage regulators snapped on and off like a crackling barrage of distant heat-guns. Below was a high gulch of the Lunar Appenines, a pattern of dazzling glare and harsh moonshadows. Ramshackle mine-buildings of prefabricated plastic straggled out from the shrouding blackness under a pinnacled ridge. Denver eyed the forbidding terrain with hair-raising panic. He checked the speed of the racing space sled, circled once, and tried to pick out a soft spot. The ship swooped down like a falling rock, power off. Denver awaited the landing shock. It was rough. Space was too cramped and he overshot his planned landing. The spacer set down hard beyond the cleared strip, raising spurting clouds of volcanic ash which showered his view-ports in blinding glare.
