Margaret Brackenreid is one of the original reoccurring characters in Murdoch Mysteries (2008) portrayed by Canadian actress Arwen Humphreys.

She is affectionately called "Mrs. B" by her MM fans who raised a campaign asking for more Mrs. B appearances. Luckily for all, MM producers and writers listened and delivered!

"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 disapproves of Thomas' drinking habits and is in a Temperance League. In Season 5, she joins a gambling club for ladies which Thomas frowns upon until she wins the jackpot.

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.

According to Arwen Humphreys, Margaret is very aware of what Thomas does when he's away.
