4 - "Downstairs, Upstairs" Rich man Percival Jenkins is found dead, shot through the head, over his breakfast. Murdoch uncovers that there have been an unusual number of maids employed by the family over the years, and that Percival had no fans either upstairs or downstairs in his household. Complicating issues, Julia is in town with her fiancé Dr. Darcy Garland (Johnathan Watton). Murdoch asks for her help in solving the case.
5 - "Monsieur Murdoch" A woman, Sophie, and her husband enlist Murdoch's help in finding her sister Monique, who has disappeared from her hotel. Curiously, Monique appeared to have keys to rooms on the fourth and second floors. Murdoch teams with a French investigator who had also been hired by the girl's father to find the missing girl, and uses photographic evidence to try and solve the crime. Dr. Ogden is back full-time in Toronto as coroner.
6 - "Dead End Street" Murdoch is able to piece together the details of a crime no one even knew had occured, based on the intricate artwork of an autistic woman, and an innovative autopsy performed by Dr. Ogden.
7 - "Confederate Treasure" A body discovered down by the docks has connections to Canada's first Prime Minister. Murdoch must tread lightly investigating a crime that may tie Canada to the American Civil War.
8 - "Dial M for Murdoch" Is a telephone operator (Rachel Wilson) really an "ear witness" to a crime, or is it a case of crying wolf? Further complicating matters is the affection that is growing between the operator, Tess, and Constable Crabtree. As the bodies pile up, her evidence must be taken seriously, and Murdoch helps devise a wire-tap to solve the crimes.
9 - "The Black Hand" A woman from Murdoch's past, Anna Fulford (Lisa Faulkner), may be implicated in a crime. Murdoch discovers that Anna's fiancé (why does every woman Murdoch cares for agree to marry someone else?), may have connections to The Black Hand. Murdoch must be careful – and so must Inspector Brackenreid, whose run for Alderman is being complicated by pressures from political factions.
10 - "Voices" Murdoch is reunited with his long-lost sister, who is an actual a sister at a convent – in fact, she is the Reverend Mother. The siblings aren't exactly experiencing a happy reunion, as two nuns at the convent are under suspicion of murder, and Murdoch is there on business, not a familial visit.
