A murder has been committed in Paris in an antique store named L' Indice. The store's strange history of unsolved murders and robberies began long before the WWII rumors of masterpieces stolen from castles on the Rhine. Jamie Litton, whose mystery writer's imagination won't let dead men, or secrets, rest in peace, moves in upstairs with hopes of discovering the truth for his next best seller. Meanwhile, Jamie's best friend, Ben Foulof, is untangling a personal mystery of his own in Japan, where he has sought refuge from the international news organization, which has condemned him as a rogue agent. Upon discovering that Jamie has ignored his warning not to return to Paris, Ben sends his best friend an alarming message, "Get out, while you still can!"
