Mimi Dagmar is a character appearing in the episode The Stitcher Society of the ITV crime drama Midsomer Murders.
Mimi was married to Toby Wagner, and a realtor by trade, working in her jointly-owned agency Dagmar & Deepdale, alongside Viola Deepdale, who was Alberta Tooms' sister. Knowing her to flirt with clients, Viola badgered Mimi with comments of not doing her job properly, and they were losing sales rather than making them. So Mimi, angry, lured her to a house to offer, and repeatedly bludgeoned her to death. She then left, only to be seen by Harry Marx. Mimi manipulated the facts and evidence to accuse her then-husband Toby of Viola's murder. It worked and Toby was arrested, but when Harry screwed up the trial, Toby walked free, but was soon hounded by a lynch mob, consisting of Mimi, Harry, Alberta and Reuben Tooms, and Viola's partner Georgie Tremayne. Reuben allowed Toby to escape to his sister Julia's pub, and then leave the village for 5 years.
