When a human heart is delivered fresh out of a body to the homicide division, Henry and Jo end up in the middle of a Jack the Ripper copycat murder investigation. But it doesn't stop there. A second killing resembles another infamous, unsolved crime: the Black Dahlia murder. Henry has seen it all before, as flashbacks show his involvement with the two original cases from two very different periods of his long life . However, Henry's anonymous caller tips him to search beyond the clues of these classic killings and leads the police squad to profile a very different, yet... He's a 200 year-old detective. You have to know there'd be a Jack the Ripper episode.
