They are actually a Canadian TV Series called "The Murdoch Mysteries" that are now playing in the US under this new name. It stars Yannick Bisson as the main character and Hélène Joy as Dr Ogden.
I had read one of the books it is based on and really liked the characters: Detective Murdoch, a young Catholic policeman who is very interested in science; and Dr. Julia Ogden, the attractive highly educated Medical Examiner; and Officer Crabtree, the inexperienced assistant who aspires to write mystery novels. Murdoch's infatuation with the doctor who helps him solve the cases is an interesting sidebar.
It is set in Victorian Toronto and often includes "real" people of the times; Buffalo Bill, Nikola Tesla, HG Wells, etc.
