Follow the signs. Find the secret. A demonic map hidden for years. A confession from beyond the grave. A train smeared in blood. An ancient evil that can kill. And one man who will do anything to connect the pieces of an infernal puzzle. Each map in this book contains a clue. A clue to a secret so monstrous that some will do anything to keep it buried. The world of Uketsu's multimillion copy-selling mysteries just got bigger. And even stranger.
