"Dial M for Murdoch" is the eighth episode of the fourth season of the Murdoch Mysteries and the forty-seventh episode of the series. It first aired on April 5 2011 (UK).


A switchboard operator with a penchant for amateur sleuthing claims she overheard the strangulation death of a young woman. Murdoch taps into the phone system to prevent a killer from striking again.

Tess Moffatt fancies herself an amateur sleuth and has cried wolf before. She takes a shine to Constable George Crabtree but is an annoyance for Detective Murdoch has they uncover an elaborate workings of an unlikely gang of thieves.

Tess is vindicated when a street urchin, who they subsequently learn went by the name of Pip, is found murdered. Dr. Ogden determines that the boy was strangled with something that left a unique mark on the his neck. She also notes that he was wearing a new suit of clothes, odd for a boy who lived on the street. Their investigation leads them to another young boy named Dorrie. It is clear that the children are the bottom rung of a gang that specializes in burglarizing homes while the occupants are away on holidays or business trips.

Meanwhile Inspector Brackenreid hits the campaign trail in his quest for a seat on City Council with his political advisor Isaac Lowe.

Murdoch’s improvised telephone wire-tapping technology uncovers an elaborately constructed criminal enterprise and a psychotic killer who will stop at nothing to preserve it.
