Based on Maureen Jennings' award-winning novels, at the end of the Victorian era, Toronto-based police detective William Murdoch uses radical forensic techniques, including fingerprinting and trace evidence, to solve some of the city's most gruesome murders. His unconventional approach often elicits skepticism from his colleagues, though he is usually supported by his boss Inspector Brackenreid, young Constable George Crabtree, and doctors/pathologists Emily Grace and Julia Ogden.  This companion looks at every aspect of all 8 seasons of the show, from the regular characters and their relationships, to the history of the period, including figures Murdoch encounters, the forensic and scientific advances he utilises, and Murdoch's most notable cases. The companion also goes behind the scenes on the show to examine every aspect of the production, including sets, costumes, music and writing.
