Midsomer Murders season 21 episode 2
Episode title: The Miniature Murders
The worlds of miniature dollhouses and real houses collide when a prolific real-estate agent is shot in front of a crowd at the unveiling of a new dollhouse collection at the Midsomer Museum of the Family. The victim had no small number of enemies: he was an unpopular landlord, an estranged husband with a new lover, and a party to a manslaughter case years ago.
