ULTIMATUM By ROGER DEE In a dingy little Indiana hotel room the fate of three worlds suddenly hung in precarious balance! [Transcriber's Note: This etext was produced from Planet Stories Spring 1950.

"That's Uncle Ivor, all right," Winant said. "Sorry he caused you so much trouble, sheriff, but I'll be glad to pay his fine. What's the charge against him?" The sheriff rubbed a palm across his drooping mustaches and looked doubtfully at the old man who sat on the edge of the cell bunk, the bald dome of his head cradled dejectedly in his hands. "You couldn't rightly say there _is_ a charge, mister," he admitted. "Your uncle popped into Ben Stuart's Drop Inn restaurant night before last with a little black box under his arm, naked as a jaybird and talking like a crazy man. "'I'm a visitor from Mars,' he says. 'Take me to your president, and quick!' Ben thought he was crazy, or drunk, and ran him out with a meat cleaver, and the old duck went down to the Warner Hotel and pulled the same goofy act. Pop Warner called me, and I went down and threw the old coot into the cooler. I knew right off that he was cracked, because I even had to show him how to put on the clothes I brought him. And the wingding he pitched when I took that black box away from him--wow!" Winant shook his head. "Poor Uncle Ivor," he said commiseratingly. "The last time he got away from us he thought he was Mahatma Ghandi, and tried to buy a bus ticket from Cincinnati to New Delhi, India. I found him, finally, in Evansville, Indiana. It's amazing how he got this far south, but then a mentally-unbalanced person can do surprising things, sometimes." The sheriff snorted. "Unbalanced, hell," he said. "The old coot's crazy as a bed-bug. Just got in from Mars, he says, and he wants the president of the United States--on the double!" He unlocked the door and Winant went inside. "It's all right now, Uncle Ivor," he said gently. The old man raised a wrinkled, leathery face and stared at him uncomprehendingly. "Let's go over to my hotel and get a good meal and a hot bath," Winant urged. "Then we'll go home again. Ready, now?" A few minutes later in the jail office the sheriff pocketed the bill Winant gave him and handed over a small lacquered metal box that was surprisingly heavy for its size. "Here's your uncle's radio," he said. "New-fangled model, I reckon. I couldn't make head nor tail of it, so I just left it alone." Winant lifted the hinged cover and looked inside the box at the neat array of tiny meters and knobs that covered the control panel.
