Season ten kicks off in grand style with a two-part mystery set in the world of Toronto debutantes, whose coming out is interrupted by the 1904 Great Fire of Toronto. Following the opener, Murdoch and the rest of Station Four find themselves embroiled in cases both fantastical and historical. From a murder involving the Olympic Champion Canadian soccer team, an investigation into a man wrongfully jailed, the introduction of H.P. Lovecraft (the master of the macabre), a wronged woman who goes on a serial killing spree, to the death of a prize pooch at a dog show, there is very little rest for Murdoch, Ogden, Brackenreid, Crabtree, James and the rest of Station Four. And as all this goes on, Murdoch tries to deliver on his promise to his wife and build her the home of her dreams. Or is it his nightmare? No matter what changes the future holds, Murdoch and the team will be there to solve each fresh mystery with tenacity and ingenuity.

Toronto 1892. William Murdoch est un jeune et brillant inspecteur qui résout des enquêtes criminelles à l'aide de techniques scientifiques d'avant garde, de l'analyse des empreintes au premier détecteur de mensonges. Son approche originale suscite les moqueries de ses collègues policiers et le scepticisme de son supérieur, mais William Murdoch est souvent le seul à trouver la piste du criminel. Sa meilleure alliée est Julia Ogden, ravissante médecin pathologiste, à l'esprit vif, qui n'a de cesse de se battre contre les préjugés de la société.
