The adventures of Percy St. John- now in a Deluxe Illustrated Edition! An unbreakable cipher, a dead priest with expensive shoes, a hermit who has conversations with saints, an angry French girl, a guardian angel with attitude, a murderous master criminal, and a gaggle of angry demons might stop an ordinary fifteen-year-old safe-cracking genius, but not Percy St.-John. He's out to prove he did not steal a mysterious ancient book that may hold the key to mankind's greatest hope and greatest danger.
