many of us, never were. It made sense. Interstellar was new and they wanted him on the ship because he was a trained observer. They wanted facts, not gibberish. Ellason nodded. "The ship disappeared." "And now," Ellason said, "you're going to try again." spent his life in our own system, and he's handpicking his own crew. We have also raised prerequisites for applicants. We don't think anything is going to happen, but if it does, we want to get an impersonal, unprejudiced view. That's where you come in. You do the observing, the reporting. We'll evaluate it on your return." "If I return," said Ellason. Captain Branson and his fifty crewmen want to return as badly as you to be as inconspicuous as possible, pressing against a bulkhead, but Captain Branson's eyes sought his several times as Branson listened to final reports from his engineers, record keepers, fuel men, Ellason liked. The captain's was a lean face, well tanned, and his eyes "Gentlemen," Branson said at last, as Ellason knew he would, "I want upon us. On loan from Transworld, he will have an observer status." He introduced him to the others. All of them seemed friendly Ellason Branson detained him after the others had gone. "One thing, Mr. Ellason. To make it easier for you, I suggest you think of this journey Ellason was startled. While he had considered the possibility, he had Captain Branson. It seems to me—" Ellason left the captain's quarters with an odd taste in his mouth. Now why had Branson said that? Why hadn't Rexroad or Phipps said something, up. He'd have to go forward to the observation dome to see that. Last view of Earth for two years. The penetration of space by large groups is the coming out from under day out. In Ellason's mind the incident, though insignificant from the Ellason had to smile at that. What did Captain Branson think of those When Ellason saw Branson about it, the captain said, "Of course I Ellason sought out Carver Janssen. He was a middle-aged man with a collect them? They're not ordinary seeds, Mr. Ellason." Branson asked him to describe the man. "Didn't you think that was important?" Branson asked in an outraged "If it is true," Branson told Ellason, "the theft must be the work of steal from his own quadrant, now would he, Mr. Ellason?" Seen in space, stars are unmoving, silent, sterile bright eyes ever 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 Ellason was present when a delegation from the Third Quadrant called on Captain Branson, demanding action. Branson remained seated behind his desk, unperturbed, saying, "I have Branson's raised hand. The group left in a surly mood. "You wonder at my reluctance, Mr. Ellason," Captain Branson said. "But suppose I assign the crew to patrol duties, the culprit isn't caught, and further incidents occur. What then? It soon becomes the crew's fault. And soon the colonists will begin thinking these things might be the crew's doing in the first place." "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." "Do you think it is a member of the crew?" Branson's eyes were bright. "No, I trust my men. I won't violate that trust." Ellason left, feeling uneasy. If he were Branson, he'd initiate an couldn't Branson see the wisdom of setting an example for the colonists? Captain Branson did not wait for the newsletter. Through the ship's in the belt and had died of a severe beating. He said that since the incident occurred in the staff section of the ship, his crew would be forced to submit to a thorough inspection in an effort to find 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 Captain Branson speaking to them. "It is not my desire to interfere in passenger affairs," he said. "Insofar as the ship is concerned, it is my duty to make certain no crewman is guilty. This I am doing. But my crew is not and cannot be a police force for you. It is up to you people to police and protect yourselves." Those assembled waited in the hall while each team of six inspected the compartments of the others. These compartments were then locked, everyone returned to his compartment, and the larger search was The captain reported that his search had been equally fruitless. "Are you out of your minds?" Branson exclaimed. "There's no law against it," Branson said, "but it's a rule of mine commit any crime. We've got him on the run, the colonists said. He's afraid to do anything, now that we've got police protection, they said smugly. of themselves. A special congratulatory message from Captain Branson put occupants to sleep as he went, taking many articles of value and leaving disorder behind. wanted to make everyone furious, he certainly succeeded. "What does he want that stuff for?" Casey Stromberg, a passenger doctor, asked. "I can see him taking my narcotics, my doctor's kit—but Ellason was busy noting it all in his book. It became filled with "Oh, yes, Mr. Ellason, we're going to get him," said Tilbury, now chief of police, cracking his knuckles, his eyes glowing at the thought. "We're bound to get him. We've got things worked out to the finest "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 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 Ellason's first thought was that he must be a stowaway, but then he remembered the face, and Captain Branson, who came to have a look at "Well, Critten," Branson roared at him, "what have you got to say for Branson looked as if he were going to kill the man himself right there was only one day out of orbit when Captain Branson sent "You're perhaps a little too good as an observer," Branson said. "Or trained to be a scapegoat. Is that right?" Critten nodded. "When great numbers are being transported, they are apt to magnify each little event because so little happens. It was my job Branson smiled. "It made the time pass quickly and interestingly for the passengers." "To say nothing of me," Critten said. "And you, Mr. Ellason, were along to observe it all," Captain Branson put in. "Interstellar wanted an accurate picture of this. If it worked, they told me they'd use it on other trips to Antheon." Ellason nodded. "No time for brooding, for differences of opinion on Captain Branson will say they were found somewhere on the ship. You Captain Branson told them to do that." Branson cleared his throat. "Ah, Ellason about that story. You Ellason said regretfully that he did understand. "The colonists will never know the truth," Branson went on. "There will
