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. Krumbine nodded. "With all those villains lurking just outside the Solar System in their invisible black ships, with planeticide in their hearts, we can't be too careful. One word transmitted from one spy to another and anything may happen. And we must bomb before they do, so as to contain our losses. Better one city destroyed than a traitor on the loose who may destroy many cities. One hundred years ago, three person-to-person postcards went through the mails—just three postcards, Potshelter!—and pft went Schenectady, Hoboken, Cicero, and Walla Walla. Here, as long as you're mixing them, try one of these oval blues—I find them best for steady swallowing."
