The realm of television crime dramas is rather crowded. With the remaining Law and Order spinoffs, there are the various CSIs, the JAG spinoffs of NCIS and NCIS:LA, and any number of cop and lawyer dramas. It's difficult to find a part of the market that isn't already saturated with the competition.
Murdoch Mysteries, which airs on City TV, fits an interesting niche, breaking new territory as a Victorian era detective story set in Toronto, which strives for period authenticity, within a fictional narrative. There doesn't appear to be a lot of competition in this admittedly small niche.
Still, it is a niche that has found its fans, including our current Prime Minister. Murdoch Mysteries is not the first show in which Stephen Harper has played a cameo role. Like former Prime Minister Paul Martin, Harper has previously appeared on Corner Gas. What's not to like, for our prime minister? Victorian crime fighters may have had limited tools, but punishments were severe. Capital punishment was still on the books, and a failed hanging formed the plot for one episode of the show. The current government's "tough on crime" persona seems to be a good match for Murdoch Mysteries, where the lead character is morally upstanding, almost to a fault. Murdoch's morality works to humanize the Toronto of the 1890s, bringing compassion to the otherwise unenlightened days of criminal enforcement.
What then, can we find of interest in Murdoch Mysteries? The fictive detective brings a scientific method to his investigations. Detective Murdoch investigates crimes using the precursors to the more modern techniques used in shows like CSI. The writers appear to take pleasure in their numerous anachronisms, by playing this man of science against adherents of other, more traditional forms of investigation, mainly coercion and interrogation.
Parts of the show have been filmed in Cambridge, Ontario. With modern signs covered up by period pieces, it retains the feel of Victorian Toronto.
While the show attempts historical accuracy, it very much plays to our modern conceptions of the Victorian era. Historical figures such as Nikola Tesla, Sir Arthur Conan Doyle, and H.G. Wells figure in the plots of several episodes, emphasizing the science and imagination that Murdoch represents.
A significant theme of Murdoch Mysteries is retrofuturism, particularly when compared to these historical figures. While the television show remains too firmly grounded in historical reality to be truly considered steampunk, there are clearly elements of several episodes which could be seen as steampunk. In particular, the season three finale, the "Tesla Effect" involved a microwave death ray machine.
Of the characters in the show, perhaps the most amusing is Constable Crabtree, whose youthful enthusiasm leads him to extrapolate towards modern technology from what he sees Murdoch use on the show. As noted on the Steampunk Scholar blog, Crabtree's role in the web series "Curse of the Lost Pharaohs" leads much closer to the realm of steampunk, incorporating other common steampunk elements.
