Extensive research did not uncover any evidence that the making. Interstellar Chief Rexroad knocked the dottle from his pipe in a tray, mask that covered his head completely." "Didn't you think that was important?" Branson asked in an outraged voice. "A man wearing a red mask?" Dievers shrugged. "This is a spaceship. How would I know whether a red mask—or a blue or green one—does or doesn't belong on a spaceship?" discounted. "If it is true," Branson told Ellason, "the theft must be the work of a psychotic. But I don't believe Jamieson Dievers. It may well be he's the psychotic." He snorted. "Red rubber mask! I think I'll have Dievers put through psychiatry." Attendant to taking notes on this incident, Ellason noted a strange watchful and accusing. To men unused to it, such a sight numbs, compresses, stultifies. He introduces a countermeasure, proof he her compartment while her husband was in the ship's library. She was taken to one of the ship's doctors, who confirmed it. She said the culprit was a husky man wearing a red rubber mask, and though her description of what he had done did not appear in the story in the newsletter, it lost no time in penetrating every compartment of "Yes," Ellason said, "but what if the intruder is a crewman?" "I know my men," Branson said flatly. "You could have a shake-down for the mask and the seed case." it was ready for ripening. Raymond Palugger was killed in the ship's hospital on the sixty-first money belt in the drawer of the small stand beside his bed. A man in a red mask was seen hurrying from the hospital area, and a staff investigation revealed that Palugger had died trying to prevent the theft of the belt. Captain Branson did not wait for the newsletter. Through the ship's speaker system, he reported that Palugger had a fortune in credits in the belt and had died of a severe beating. He said that since the mask, the seed case, the money and the man. "I will not countenance such an act by a crewman," Branson said. "If and when he is found, he will be severely dealt with. But he might not "How can we protect ourselves without stunners?" one colonist called out. "Has Red Mask a gun?" Branson retorted. "It seems to me you have a better weapon than any gun." "What's that?" everyone returned to his compartment, and the larger search was conducted. It took twenty hours. No mask was found. No mask, no case, no money, no man. The captain reported that his search had been equally fruitless. At another assembly the following day it was decided to make the Mask. The Quadrant Council held periodic meetings to set up a method of trial for him when he was caught. It was all recorded in the newsletter and by Keith Ellason. During sleep time on the seventy-ninth day Barbara Stoneman, awakened by a strange sound, sat up in the bed of her compartment to find a man in a red mask in her room. Her cries brought neighbors into the corridor. The flight of the man was witnessed by many, and several men tried to stop him. But the intruder was light on his feet and fast. He "There's no law against it," Branson said, "but it's a rule of mine that no weapons are to be issued en route." "If we had had a gun, we'd have got Red Mask," Tilbury said. "And I might have a murder on my conscience." Tilbury said, "We've also thought of that. Suppose you supply us with the corridors—eight on at a time. Ellason observed that for the first time the passengers seemed relaxed. Let Red Mask move against armed men, they said. Yeah, let him see what happens now. Red Mask did. On the 101st day he was seen in a corridor in Quadrant Four. Emil Pierce, policeman on duty, managed to squeeze off several shots at his retreating figure. Red Mask was seen again on the 120th day, on the 135th day, and the 157th day. He was seen, shot at, but not hit. He was also unable to commit any crime. The colonists settled down to living out the rest of the voyage until the landing on Antheon. But on the 170th day calamity struck. Red Mask appropriated one of the stunners, made his way down one whole corridor section in Quadrant Two, put occupants to sleep as he went, taking many articles of value and Ellason interviewed as many victims as he could, noted it all in his book. The things taken were keepsakes, photographs and items of personal value. It seemed to be the work of a madman. If Red Mask wanted to make everyone furious, he certainly succeeded. "What does he want that stuff for?" Casey Stromberg, a passenger trigger-happy policemen thought their movements suspicious, about one man's suspicion of another and the ensuing search of compartments, people who saw Red Mask here, saw him there. Hardly a day went by without some new development. "Oh, yes, Mr. Ellason, we're going to get him," said Tilbury, now chief detail. He won't be able to get through our fingers now. Just let him make so much as a move." "And what will you do when you get him?" "Kill him," Tilbury said, licking his lips, his eyes glowing more fiercely than ever. "Without a trial?" "Oh, there'll be a trial, Mr. Ellason, but you don't think any jury'd let him live after all the things he's done, do you?" Red Mask was stunned in Quadrant Four in a corridor by a policeman named Terryl Placer on the 201st day. The criminal was carried to the assembly room surrounded by guards, for he surely would have been mauled, if not killed, by angry colonists who crowded around. In the assembly hall his mask was whipped off. The crowd gasped. Nobody knew him. Ellason's first thought was that he must be a stowaway, but then he Harrel Critten and he was a record keeper third class. "Well, Critten," Branson roared at him, "what have you got to say for "Go to hell," Critten said quietly. As if it were an afterthought, he seem to be much doubt about the outcome, for Critten didn't help his do with the loot, Critten?" Critten looked him square in the eye and said, "I threw it out one of They executed Harrel Critten on the morning of the 270th day with disposed of his body through a chute. It was all duly recorded in Keith Ellason's notebooks. Dying is easy for a Nilly. Especially if it's arranged for beforehand, "Hello," Critten said, grinning from ear to ear. matter, Critten did a good job.

"When great numbers are being transported, they are apt "To say nothing of me," Critten said. small matters. Just time to hate Mr. Critten. Unanimously." "Probably," Critten said, "you are wondering about the execution." Critten grinned again. "She played right into our hands. She ran out Captain Branson told them to do that." "And the murder?" "Raymond Palugger died in the hospital all right, but he died from his illness on the operating table. We turned it into an advantage by making it look suspicious." Ellason brightened. "And by that time everybody was seeing Red Mask everywhere and the colonists organized against him." "Gave them something to do," Branson said. Critten sighed. "And I'll have to be caught again."
