Germany, 1944: the Ace of Clubs is on a solitary mission to bomb a rural country estate in Germany, but the mission is so top secret. Flight Lieutenant Fletch Wrath Hannah has no idea why they've been commanded to break away from the bomber stream. Suddenly, out of nowhere, the plane is attacked by German Junkers and Wrath has to give the command to bale out as the plane crashes over Nazi Germany.Germany, present day: a bulldozer on a construction site uncovers the remains of the long-lost Second World War bomber and so begins a treacherous international journey from the crucifixion of Jesus at Golgotha to the Crusades, the Inquisition, witch hunts, Satanism, exorcism, the Reichskonkordat and modern archaeological discoveries. Lawyer/historian Wyatt Rook and Liz Hannah must solve a series of whodunits, locked-room murders, as well as biblical mysteries, to unravel the Judas puzzle: the Achilles heel of the New Testament. Blocking them at every turn is the Legionary of Christ, a present day crusader backed by a secret inquisition that will stop at nothing to make sure the Judas puzzle remains unsolved.
