A modern-day Munich bookseller is caught in a decades-old conspiracy in this thriller by the bestselling author of The Hangman's Daughter series. In 1886, Ludwig II, the Fairy-tale King of Bavaria, was deposed after being declared insane by doctors who had never met him. He died mysteriously soon thereafter, his eccentric and beautiful castles his only legacy. In The Ludwig Conspiracy , master of historical suspense Oliver Pötzsch brings the Mad King back to life. An encoded diary by one of Ludwig's confidants falls into the hands of modern-day rare-book dealer Steven Lukas, who soon realizes that the diary may bring him more misery than money. Lukas teams up with a beautiful art detective, Sara Lengfeld, to investigate each of Ludwig's three famous castles for clues to crack the diary's code as mysterious thugs and Ludwig's fanatical followers chase them at every step. Just what in the diary could be so explosive?
