"That's all, Mr. Carre," he said. "You can go in." They preceded him into the reception room, advanced to the rear wall and pushed a series of buttons in a complex pattern. A double door, made of metal instead of the innocent oak it had seemed to be, slowly swung open. Philip Hartridge rose from his desk and extended his hand. "Awfully good to see you, Carre," he said. "It must have been nearly ten years. Sorry you've never come over to see us sooner. We're very proud of Script-Lab. How are things?" "Not bad," said Herbert. "I'm still feeling overwhelmed by the elaborate protective system you have here. What explains the body-guards? I didn't suppose this laboratory was classified." Hartridge leaned back in his chair. "It's not classified. Those men are here to protect me from possible violence." "Violence? Great Gamma, do you mean personal threats?" "Yes. Only last week, my 'coptor exploded a few minutes after I started the motor. By a lucky chance, I had gone back to the house to get my brief-case. But someone had certainly tried to kill me." "Why on earth, Hartridge, should some one--" "It might be one of several people," he said. "But I think it's my brother Ben. He would, of course, like to have my share of the money our father left us. But I'll take care he doesn't get it." He grinned, and patted his hip. "It's rather more likely to be the other way around. But we won't waste time in trivialities, Carre. Ludwig called me. I know you want to see our set-up here. Come in and see the machines." They walked through another set of double doors and into the Laboratory. The noise was deafening. Twenty enormous machines sat in the room. Each was contained in a dull plastic case, and the control panels were a maze of dials, buttons, and red and green indicator lights. An electric typewriter was connected to and operated by each machine, and through each typewriter ran an endless roll of paper, which emerged to be cut off into eleven-inch lengths by automatic knives. "How do you stand the noise?" asked Carre. "Why don't you use Silent Typers?" "Oh, the machines don't mind the noise. Silent Typers would be an unnecessary expense, and as a matter of fact, I've come to like the sound. It's soothing, after a time." Carre strolled slowly, rather mournfully, from one monster to another, glancing at the emerging manuscripts. "The rate of output," said Hartridge, "is not less than a hundred words a minute, and they never have to stop to look up their facts, or to struggle with a balky plot. Can you do as well?" "I wish I could," said Carre. "I know so little about electronics. Do the machines use much current?" "No, that's another of their virtues, they're very economical. The tubes are so efficient that all twenty machines are run from this one source, right here--Don't touch it! It's not ordinary house current, you know. We start with eight thousand volts,--it saves on metal and transformers."
