 Which term best describes the relationship between Arvid 6 and Tendal 13?
Transcriber's Note: This etext was produced from Space Science Fiction May 1952. THE ULTROOM ERROR by JERRY SOHL Smith admitted he had made an error involving a few murders—and a few thousand years. Ultroom error. Tendal 13. Arvid 6. Kanad transfer out of 1609 complete, intact, but too near limit of 1,000 days. He was gurgling happily, examining a ball, a cheese grater and a linen baby book, all with perfunctory interest. It was her brother who lived in Kankakee. As he did so the baby's knees hit the side of the play pen and young Laughton let out a scream—half from hurt and half from sudden lack of confidence in his new handler. Around the corner and after the man came a snarling mongrel dog, eyes bright, teeth glinting in the sunlight. The man did not turn as the dog threw himself at him, burying his teeth in his leg. "I tell you, the man said he was my brother and he made me think he was," Nancy told her husband for the tenth time. I can't say I dreamt it because there was Reggie with his bleeding knees, squalling for all he was worth on the grass—Oh, I don't even want to think about it."

He put it by the stairs, ready for use, fully loaded, leaning it against the wall next to the telephone stand. I think it's $32, isn't that right?" Martin went over to his desk, opened it and started looking for his checkbook. Dr. Stuart stood by him, making idle comment until Dr. Tompkins came down the stairs with the sleeping baby cuddled against his shoulder. The figure of a woman ran from the house, retrieved the now squalling infant and ran back into the house. Once inside, Nancy slammed the door, gave the baby to the stunned Martin and headed for the telephone. One of them was the same man who tried to take the baby this afternoon. They hypnotized my husband—" "Yes, I know, Mrs. Laughton. There's supposed to be two of them. Shot with a .30-.30."
