Why it matters
Planning paperwork, architectural taste and village influence form a surprisingly efficient machinery for murder.
Great Pelfe's conservation society erupts when the modern Swanscombe House features in an open-gardens event. Members publicly accuse the architect, builder and officials of corruption connected with a further planning application.
A leading campaigner is stabbed, evidence disappears and people linked to the alleged scheme die in deaths shaped by their professions. Barnaby and Jones realise that somebody is eliminating a chain of participants rather than merely winning a design argument.
Break the seal: reveal the finding
The corruption allegations are substantially true, and the killer is covering a role in the scheme. The sequence of deaths follows who could expose the next link.

Break a second seal: reveal the verified killer
Verified killer
Liz GerrardLiz killed Maureen Stubbs when Maureen was about to expose the development scam, then killed Clifford Bunting after his blackmail and Geoff Rogers when he wanted out. Angela Lawrence assisted the wider conspiracy but is not identified as a physical killer; Liz's attempt to poison Norman Swanscombe and frame James Otley was interrupted.
Verified motive
Liz killed to protect the covert Pelfe Chase supermarket scheme, its promised financial future and the professional career exposure would destroy: Maureen carried proof, Bunting tried blackmail and Rogers became dangerous when he wanted out. She then tried to kill Swanscombe and use the stolen ketamine and exotic toxin to frame Otley.
