Flesh and Blood (A Scarpetta Novel)

Details: Dr. Kay Scarpetta's birthday is approaching, and she's about to leave for Miami with her FBI profiler husband, Benton Wesley when she notices seven pennies on a wall behind their Cambridge home. Is this a game for kids? If that's the case, why are all of the coins from 1981 so shiny and new? Her phone rings, and Detective Pete Marino informs her that a homicide has occurred five minutes away.
