JERRY SOHL Smith admitted he had made an error involving a few his daily dose of sunshine. He was gurgling happily, examining a ball, a cheese grater and a linen baby book, all with perfunctory interest. When she looked up again she noticed a man walking by—except he 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 man dropped the screaming child on the lawn and turned to the dog. Joe seemed off balance and he backed up confusedly in the face of the Martin Laughton sighed. "I can't understand why you believed him. It's just—just plain nuts, Nancy!" "Don't you think I know it?" Nancy said tearfully. "I feel like I'm going crazy. I can't say I dreamt it because there was Reggie with his table and she sobbed. "Nancy, for heaven's sake, of course I believe you. I'm trying to think it out, that's all. We should have called the police." Nancy shook her head in her arms. "They'd—never—believe me either," she moaned. They found Reggie peacefully asleep in his crib in his room upstairs. windows locked. I'll see that the prowl car keeps an eye on the house. Call us if anything seems unusual or out of the way." Nancy had taken a sedative and was asleep by the time Martin finished infant and ran back into the house. Once inside, Nancy slammed the telephone. "One of them was the same man!" she cried. Martin gasped, sinking into a chair with the baby. "I believed them," he said slowly and uncomprehendingly. "They made me believe them!" guy carrying your baby, don't you think?" "I shot him in the legs. The other—the other turned and I shot him in the chest. I could even see his eyes when he turned around. If I hadn't pulled the trigger then ... I don't want to remember it." The policemen went out. "Thank God you woke up, Nancy," Martin said. "I'd have let them have Nancy, who was rocking the boy, narrowed her eyes. "I wonder why they want our baby? He's just like any other baby. We don't have any money. We couldn't pay a ransom." trees. It would be a crime to keep Reggie inside on a day like this, keep an eye on Nancy and Reggie and to call the police at the first street for any strangers, ready to flee inside if need be. Reggie just gurgled with delight at the change in environment. This peaceful scene was disturbed by a speeding car in which two men were riding. The car roared up the street, swerved toward the parkway, tires screaming, bounced over the curb and sidewalk, straight toward the child and mother. Reggie, attracted by the sudden noise, looked up to see the approaching vehicle. His mother stood up, set her palms against her cheeks and shrieked. The car came on, crunched over the play pen, killing the child. The mother was hit and instantly killed, force of the blow snapping her spine and tossing her against the house. The car plunged on into a tree, hitting it a terrible blow, crumbling the car's forward end so it looked like an accordion. The men were thrown from the machine. "We'll never be able to prosecute in this case," the states attorney said. "At least not on a drunken driving basis." "I can't get over it," the chief of police said. "I've got at least six men who will swear the man was drunk. He staggered, reeled and gave the usual drunk talk. He reeked of whiskey." knows where." "Getting back to the man who ran over the child and killed Mrs. Laughton. Why did he pretend to be drunk?" It was the chief's turn to shake his head. "Your guess is as good as mine. There are a lot of angles to this case none of us understand. It on file in Washington, so we've discovered. We've had him in jail for a week and we've all taken turns questioning him. He laughs and admits his guilt—in fact, he seems amused by most everything. Sometimes all alone in his cell he'll start laughing for no apparent reason. It gives you the creeps." driver's license. And there's no duplicate of that in Springfield, in case you're interested." The man who had laughingly told police his name was John Smith lay on his cot in the county jail, his eyes closed, his arms folded across his chest. This gave him the appearance of being alert despite was Arvid 6—had lain in that position for more than four hours, when suddenly he snapped his eyes open and appeared to be listening. For a moment a look of concern crossed his face and he swung his legs to the floor and sat there expectantly. the Ultroom!" "I'm sorry, Tendal," the man on the cot said. "I didn't think—" "You're absolutely right. You didn't think. Crashing that car into that tree and killing that woman—that was the last straw. You don't "You didn't have to come along at all, you know," Arvid 6 said. "How well I know! How sorry I am that I ever did! It was only because reaches the height of stupidity and volunteers to help Arvid 6 go back He snorted. "I still can't believe I was ever that stupid. I only prove it when I pinch myself and here I am. ours when we were ambushed by Anthony's men. And worst of all, that English barmaid you became engrossed with at our last stop in 1609, when her husband mistook me for you and you let him take me apart piece by piece—" the poor thing by suggesting suffocation to it that night. "And speaking of that night, you remember we agreed I was to do the talking. But no, you pulled a switch and captured Martin Laughton's attention. 'I came as soon as I could, Martin,' you said. And suddenly didn't even come close to getting the child. "Still you wanted to run the whole show. 'I'm younger than you,' you said. 'I'll take the wheel.' And the next thing I know I'm floating in space halfway to nowhere with two broken legs, a spinal injury, concussion and some of the finest bruises you ever saw." These twentieth century machines aren't what they ought to be," Arvid 6 said. "You never run out of excuses, do you, Arvid? Remember what you said in the Ultroom when you pushed the lever clear over and transferred in." Tendal 13 turned and looked steadily and directly at Arvid 6. "Do you know what I think? I think you deliberately pushed the lever over as far as it would go just to see what would happen . That's how simple I think it was." Arvid 6 flushed, turned away and looked at the floor. anything—you said we shouldn't dematerialize in front of anybody." "That's right." "Well, I didn't know what to do. I could see they thought I was drunk, so I was. But they had a blood sample before I could manufacture any alcohol in my blood, although I implanted a memory in them that I reeked of it." He laughed. "I fancy they're thoroughly confused." "And you're thoroughly amused, no doubt. Have they questioned you?" "And you amused yourself with him." "I suppose you'd think so." license—" "Never mind. It's easy to see you've been your own inimitable self. Believe me, if I ever get back to the Ultroom I hope I never see you laughed as he saw the jailer's eyes bulge. "Arvid!" The jailer watched stupified as the two men vanished in the middle of a violent argument.
