For the next three days, I was unable to reach Mr. Johnson, so I did something foolish, I went ahead and cracked the file. Three days. It took me that long, three days and three nights. I don’t think I slept a total of four hours. It was one of the most difficult, frustrating, and wonderful experiences of my life. Mycroft’s programming is beautifully ornate and complex, weaving together strands of data like a Bach fugue. When it finally opened to me like a butterfly stretching new wings, I wept tears of joy and relief. What it revealed was . . . astounding.
