Boat People

"For generations, the people of Gotham City have looked to Wayne Manor as the embodiment of wealth and high society. But when construction crews discover a corpse buried on the grounds, the venerable family estate is embroiled in scandal. Is someone trying to frame billionaire playboy Bruce Wayne for a shocking and heinous crime? Hardly. Forensic scientists determine the body has been decomposing for at least thirty years, and the likely murderer was Bruce Wayne's father, Dr. Thomas Wayne. Torn between the need to protect his family's honor and his obligation to deliver justice, Batman sets out to solve the coldest of cases, using nine mysterious clues (all included throughout [the] book as removable facsimiles)"--P.
