Why it matters

The tiny houses offer a neat visual counterpoint to a case driven by very real homes, landlords and broken relationships.

Estate agent and landlord Alexander Beauvoisin is killed in front of a crowd gathered for a new dolls-house display at the Midsomer Museum of the Family. His record as a landlord and his separation from Fiona create no shortage of people with reason to resent him.

A second death complicates the apparent romantic triangle, while Alexander's new partner is revealed to have entered his life under a professional identity. Barnaby and Winter connect the victims through an earlier incident and the consequences of property decisions made by the same circle.

The killings lead back to an earlier incident in which housing, betrayal and official responsibility became inseparable for those involved.

A public murder

Alexander is killed during an unveiling rather than in private, making the crowd, sightlines and museum display part of the opening puzzle.

The chronology is the reference for the credits shown here. A programme homepage does not independently verify a filming date or every production detail. Where multiple transmission dates are listed, territory attribution needs checking. Story, teleplay and adaptation distinctions require the original credit wording; links to external synopses may reveal plot details.

Verified killer

Carys Nicholson

Carys shot Alexander Beauvoisin to stop him discovering Nicco Rainsford's body, then killed Jemima Starling after Jemima followed her while she moved it. Maxine Dobson had shot the intruding Nicco in self-defence; Carys concealed that death and killed the two present-day victims while trying to protect Maxine.

Verified motive

Carys acted to protect Maxine after Maxine shot the intruding Nicco in self-defence. She concealed the body, killed Alexander when his survey would expose it and Maxine risked prison, then killed Jemima in panic after Jemima followed the body move and discovered the secret; Maxine's original shooting remains separate.
