quarters and the mess hall. The ship was gigantic; it took twenty minutes, for the ship's complement to assemble in the captain's control hall. There were fifty-seven men, eighteen officers. They stood in casual formation and gaped at the life-scanner's screen. The spacesuited figure had not moved. Captain Pinkham said, "One question. Which of you gadget-happy jokers gimmicked up the scanner on us? Who did this?" Nobody said anything. Only one man smiled: Lieutenant Joe Silver, a very bright, very ambitious big cub who was on his second extragalactic expedition and obviously had visions of earning his captain's bronze comets within the year. Joe was a rather unpleasant young piece of beef, thought Pink; but he wouldn't pull practical jokes. He was too bloody serious. If he smiled, it was probably because he was enjoying the Captain's evident bewilderment. "Then it isn't a joke," said Pinkham. "Three of you outside repairmen get into your suits and bring that in." He gestured at the silent figure on the motionless little world of the scanner. "Jerry says it's alive. Handle with care." He waved them his dismissal. Some twenty minutes later he watched the screen as the three crewmen descended to the surface of the planetoid, pried loose the double anchor which the unknown Earthman had sunk into the ball's crust to hold him steady on the almost-gravityless world, lifted the bulky figure and leaped upward, like thick but weightless panthers carrying their prey, into the open air-lock. The spacesuited stranger had not moved in the slightest. Yet the scanner, which was never wrong, said that within the armor of the suit was life. Pinkham sat staring at the blanked-out screen, and a queer chill began to crawl up his neck. An old slang phrase came to his mind, and wouldn't leave. How come? How come? How come? CHAPTER II Pink and Jerry and Joe Silver walked around and around the spacesuit. Bill Calico, the astrogator, and Washington Daley, the senior lieutenant, sat in front of it on stools covered with Venusian joerg-hide, going through a routine of flippant gags that thinly disguised their bafflement. Finally Pinkham said, "When were these suits invented?" "2144," said Joe Silver.
