The cryptographer

John Law is Anna's latest client, and her most formidable challenge. The 'Cryptographer', people call him. He is mysterious and charming, the world's first quadrillionaire, the inventor of an unbreakable code, the creator of the world's first great electric currency. In the new millenium, it is no longer quite acceptable to admire the rich. But Law is both distrusted and admired more than most, more than Anna understands. That will have to change. Rule number one: information is the inspector's greatest weapon. And Anna needs to know - what is it that a man like John Law would seek to hide, and why?
