Why it matters
Children's evidence overturns the first reading of the death and gives the investigation an unusually clear moral centre.
An apparent suicide in Setwale Wood points instead to a land dispute, two observant children and a concealed family story.
Susan Bartlett is discovered in Setwale Wood with evidence suggesting suicide. Two children say they saw the body earlier than the official timeline allows, convincing Barnaby and Troy that the scene was arranged.
The wood is already at the centre of litigation between the Bartlett and Harrington families over development. When James Harrington is also killed, the inquiry expands into old beliefs about the woodland, private relationships and a family truth that would alter more than the court case.
Break the seal: reveal the finding
The staged suicide and later murder protect a secret about the children and the two households; the development dispute is real but not the whole motive.
