Leo frowned and reached for his mouse, but the cursor wouldn't move. Suddenly, the notebook started filling itself with code. Hundreds of lines per second scrolled past, far faster than any human could type. It wasn't just math; it was a map. The software was pulling data from his hard drive, his browser history, and even his webcam.
