_Do not be frightened of me, Jane. I am no caveman except for my hair. I am not insane. I am emotionally disturbed, but in a way that no machine has ever described to me. I want only your happiness._ _Sincerely_, _Richard Rowe_ Krumbine slumped back in his chair, which braced itself manfully against him, and looked long and thoughtfully at Potshelter. "Well, if that's a code, it's certainly a fiendishly subtle one. You'd think he was talking to his Girl Next Door." Potshelter nodded wonderingly. "I only read as far as where they were planning to blow up Grand Central Spaceport and all the guides in it." "Judas Priest, I think I have it!" Krumbine shot up. "It's a pilot advertisement--Boy Next Door or--that kind of thing--printed to look like hand-writtening, which would make all the difference. And the pilot copy got mailed by accident--which would mean there is no real Richard Rowe." At that instant, the door dilated and two blue detective engines hustled a struggling young man into the office. He was slim, rather handsome, had a bushy head of hair that had somehow survived evolution and radioactive fallout, and across the chest and back of his paper singlet was neatly stamped: "RICHARD ROWE." When he saw the two men, he stopped struggling and straightened up. "Excuse me, gentlemen," he said, "but these police machines must have made a mistake. I've committed no crime." Then his gaze fell on the hand-addressed envelope on Krumbine's desk and he turned pale. * * * * * Krumbine laughed harshly. "No crime! No, not at all. Merely using the mails to communicate. Ha!" The young man shrank back. "I'm sorry, sir." "Sorry, he says! Do you realize that your insane prank has resulted in the destruction of perhaps a half-billion pieces of first-class advertising?--in the strangulation of a postal station and the paralysis of Lower Manhattan?--in the mobilization of SBI reserves, the de-mothballing of two divisions of G. I. machines and the redeployment of the Solar Battle Fleet? Good Lord, boy, why did you do it?" Richard Rowe continued to shrink but he squared his shoulders. "I'm sorry, sir, but I just had to. I just had to get in touch with Jane Dough." "A girl from another hive? A girl you'd merely gazed at because a guide happened to blow a fuse?" Krumbine stood up, shaking an angry finger. "Great Scott, boy, where was Your Girl Next Door?" Richard Rowe stared bravely at the finger, which made him look a trifle cross-eyed. "She died, sir, both of them." "But there should be at least six." "I know, sir, but of the other four, two have been shipped to the Adirondacks on vacation and two recently got married and haven't been replaced." Potshelter, a faraway look in his eyes, said softly, "I think I'm beginning to understand--"
