Detective Lincoln Rhyme, the foremost criminalist in the NYPD, is on the hunt for an elusive murderer, the Coffin Dancer. He's a brilliant hitman who changes his appearance even faster than he adds to his trail of victims, only one of whom has lived long enough to offer a clue: the assassin has an eerie tattoo on his arm of the Grim Reaper waltzing with a woman in front of a casket.
