Blake was a professional stage magician who used his skills to solve crimes and help the helpless. Years earlier, Blake had been in prison on a trumped-up espionage charge in an unnamed country in South America. He discovered a way to escape with his cellmate, which began his interest in escapology. The cellmate died and left him a fortune. The escape, apparently followed by exoneration of the false charges that had led to it, led to Blake's pursuit of a career in stage magic, which made him famous. He never forgot his unjust imprisonment, and it motivated him to seek justice for others.
