"No, no, Krumbine." Potshelter nervously popped a square orange tablet into his mouth. "It's a hand-written letter." Krumbine watched him. "I never mix tranquilizers," he boasted absently. "Hand-written, eh? You mean that the message was imprinted on a hand? And the skin or the entire hand afterward detached and sent through the mails in the fashion of a Martian reproach? A grisly find indeed, Potshelter." "You still don't quite grasp it, Krumbine. The fingers of the hand move the stick that applies the ink, producing a crude imitation of the printed word." "Diabolical!" Krumbine smashed his fist down on the desk so that the four phones and two-score microphones rattled. "I tell you, Potshelter, the SBI is ready to cope with the subtlest modern deceptions, but when fiends search out and revive tricks from the pre-Atomic Cave Era, it's almost too much. But, Great Scott, I dally while the planets are in danger. What's the sender's code on this hellish letter?" "No code," Potshelter said darkly, proferring the envelope. "The return address is--hand-written." Krumbine blanched as his eyes slowly traced the uneven lines in the upper left-hand corner: _from_ Richard Rowe 215 West 10th St. (horizontal) 2837 Rocket Court (vertical) Hive 37, NewNew York 319, N. Y. Columbia, Terra "Ugh!" Krumbine said, shivering. "Those crawling characters, those letters, as you call them, those _things_ barely enough like print to be readable--they seem to be on the verge of awakening all sorts of horrid racial memories. I find myself thinking of fur-clad witch-doctors dipping long pointed sticks in bubbling black cauldrons. No wonder Pink Wastebasket couldn't take it, brave girl." * * * * * Firming himself behind his desk, he pushed a number of buttons and spoke long numbers and meaningful alphabetical syllables into several microphones. Banks of colored lights around the desk began to blink like a theatre marquee sending Morse Code, while phosphorescent arrows crawled purposefully across maps and space-charts and through three-dimensional street diagrams. "There!" he said at last. "The sender of the letter is being apprehended and will be brought directly here. We'll see what sort of man this Richard Rowe is--if we can assume he's human. Seven precautionary cordons are being drawn around his population station: three composed of machines, two of SBI agents, and two consisting of human and mechanical medical-combat teams. Same goes for the intended recipient of the letter. Meanwhile, a destroyer squadron of the Solar Fleet has been detached to orbit over NewNew York." "In case it becomes necessary to Z-Bomb?" Potshelter asked grimly.
