I encourage everyone to read the novel upon which this wonderful series is based. I read it years ago, and it has stayed with me; this TV series is doing the same. They have captured the period the same way the novel did. The incredible sets, the corruption, the squalor vs. the obscene wealth,
the underbelly of the time . . . it is all here. The acting is also top-notch, as all of the principle characters seem so much of that era, rather than actors playing costume. And to see "old" pros like Grace Zabriske, Ted Levine, and Sean Young pop up in secondary roles is a real treat. The crimes themselves offer the series (as it did in the novel) the opportunity to delve into various themes: psychology, policing, class, sexual orientation, forensics, etc., and the series also provides a peek at the changing world of the time: telephones, fingerprinting, Socialism, women's roles, typewriters, and more. I think this series is a must-watch for fans of both criminal procedurals, historical dramas, and psychological suspense.
