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\u2019s out to prove he did not steal a mysterious ancient book that may hold the key to mankind\u2019s greatest hope and greatest danger. E.A. Allen is a History Professor, cattle farmer, and retired C.I.A. intelligence officer. When he\u2019s not out chasing straying cows that have no respect for fences, or tracking-down undergraduates who have no respect for assignment deadlines, he\u2019s at his desk, writing mysteries in the great tradition of Sir Arthur Conan Doyle, Agatha Christie, and Dorothy L. Sayers.
