SEASON FINALE: The last episode of the season provides the same plot device – a murder – familiar to many episodes of this period drama series, set in the era and neighborhood of Jack the Ripper. But this time, the victim is a visiting American journalist – which means it’s big news, at least to the British tabloids of Fleet Street. And women figure in this episode without being victims, as with bordello entrepreneur Long Susan (MyAnna Buring, pictured), who scrambles tonight to maintain her profitable enterprise.
