"Alice wouldn't dare." And for a moment he looked so frightening that I couldn't help but believe it -- I couldn't imagine someone brave enough to cross him. "Alice already saw it, didn't she?" I guessed. "That's why the things she says upset you. She knows I'm going to be like you... someday." "She's wrong. She also saw you dead, but that didn't happen, either." "You'll never catch me betting against Alice." We stared at each other for a very long time.

"I don't believe you," he said gently. "I'm not going back to sleep." "You need rest. All this arguing isn't good for you." "So give in," I hinted. "Nice try
a pretty good pencil-and-paper analog of the PURPLE machine. S.I.S. then constructed a mechanism that would do automatically what the cryptanalysts could do manually with their tables and cycles. They assembled it out of ordinary hardware and easily available pieces of communication equipment, such as the selector switches used for telephones. It was hardly a beautiful piece of machinery, and when not running just right it spewed sparks and made loud whirring noises. Though the Americans never saw the 97-shiki O-bun In-ji-ki, their contraption bore a surprising physical resemblance to it, and of course exactly duplicated it cryptographically. S.I.S. handed in its first complete PURPLE solution in August of 1940, after 18 or 20 months of the most intensive analysis. In looking back on the effort that culminated in this, the outstanding cryptanalytic success in the whole history of secret writing up to its time, Friedman would say generously:
