What it is
Set in Toronto at the dawn of the 20th century, Murdoch Mysteries is a one-hour drama series that explores the intriguing world of William Murdoch, a methodical and dashing detective who pioneers innovative forensic techniques to solve some of the city's most gruesome murders. Murdoch's colleagues include the love of his life, coroner and psychiatrist Dr. Julia Ogden, a staunch ally who shares the detective's fascination for science; Constable George Crabtree, Murdoch's eager but sometimes naïve right-hand man; Inspector Brackenreid, Murdoch's skeptical yet reluctantly supportive boss; and coroner Dr. Emily Grace, Dr. Ogden's protégé.
