In the 1890’s Police Inspector William Murdoch uses unheard of forensics to solve gruesome mysteries aided by female coroner Dr. Julia Ogden. In season 3, William (Yannick Bisson, “Too Late to Say Goodbye”) finds himself in Bristol, England with no memory of who he is and being pursued by the British authorities accusing him of murder. Murdoch must use all his wiles to get back home and prove himself innocent. This season, investigations take William into the disturbing world of Eugenics, the murky realm of art theft, the circus and the Freemasons. When a long-buried secret bubbles to the surface, Dr Julia Ogden (Hélène Joy, Durham County), suddenly faces the choice of staying or heading for a new job in America, forcing Murdoch to confront his greatest challenge, to win back the love of his life.
