"Margaret Brackenreid is the ideal counterpart to her classic Victorian husband. Equally a product of the times, Margaret may not buy into the votes for women, but she has learned from the women who went before her how to manage a husband without him knowing." – Investigating Murdoch Mysteries
Margaret Brackenreid is married to Inspector Thomas Brackenreid and together they have two young boys. Margaret is a very passionate woman, who is always very determined in everything she does.
Constable Brackenreid was only on the force two weeks when he arrested Margaret. She had gotten into a tiff over the lunch special at Maisy’s,“…such a tart tongue, full of sass, even then.” (ep 807)
Thomas Brackenreid had just come out of the army when Margaret's father asked him to join the family's plumbing business. Margaret thought he'd have been a good plumber, but his heart was set on the police force. Married to a policeman, she knew what she was getting into, no point in complaining about the long hours– and the worry. But still... she does worries after they had the two boys (ep 304).
Margaret does not like the opera but instead enjoys classical music on their gramophone. She is a good cook, bakes her own bread, and is noted for her excellent plum pudding at Christmas by Murdoch.
