I came upon this series several months ago and am hooked on it.
Based on novels by Maureen Jennings, "Murdoch Mysteries" follows young detective William Murdoch. In a series of stories taking place in Toronto during the 1890s and early 1900s, several challenging murder cases arise. Murdoch uses up-and-coming forensics techniques and an unconventional approach, which often elicit skepticism from his fellow officers and his boss. Coroner Julia Ogden becomes Murdoch's number one ally, and they make a top-notch team, but he must struggle against tradition and prejudice to solve some of the city's most-gruesome murders.
The characters, the costumes, the attention to details, the history of Toronto back then, the topics that they cover are so worthwhile. I highly recommend it!
Another thing – some of the details involve real people – and I have to check good ol google that these persons did indeed exist back then and they resemble how that person would walk or talk etc.
