Murdoch Mysteries S04E05 - Monsieur Murdoch

Julia is getting married to Rafe in a week - the letter she wrote to Murdoch confessing her love for him is lying beneath his desk blotter and he has no idea it exists. On top of his heartbreak, he has made no progress on a case involving a young French woman who had arrived in Toronto to visit her married sister and then vanished without a trace. The case is further complicated when Murdoch arrests a dashing young Frenchman breaking into a suspect's apartment, only to learn that he is Detective Marcel Guillaume, who has been hired by the disappeared woman's father.

Note: Guillaume is the real-life inspiration for author Georges Simenon's main character, Inspector Maigret.
