A cryptic message left by a German cabal at the end of World War Two. An ancient prophecy hidden in the works of Poe. And a string of murdered scientists. Somehow they're all connected. When Henry Warland agrees to help his beautiful skydiving partner, Mary Carver, with a "small errand," he has no idea what he's gotten himself into. Grave-robbing, stolen goods, and a psychiatric patient with a wild theory about... well, everything... and that's just the beginning. Because he soon finds himself drawn into a quest to solve the greatest mystery of all time. As Henry and Mary journey across Europe hunting for clues-all while being pursued by a fanatical, murderous cult-their trail leads them to uncover secrets that were meant to remain buried. If they can survive long enough to find the truth, their greatest challenge may lie in knowing what to do when they find it.
