Why it matters

The investigation splits neatly between Jones inside the Oblong Foundation and Barnaby examining the manor's less spiritual history.

Lucy Oliver disappears after joining the Oblong Foundation, a New Age group operating from Malham Manor. Because she is connected to friends of pathologist George Bullard, Barnaby agrees to investigate while Jones uses his recent undercover training to enter the group as an inductee.

The manor belongs to Ruth Lambert, whose parents died in a boat explosion, and Barnaby suspects that their history is connected to the present disappearance. When a Foundation leader is killed, the retreat's language of reinvention begins to look useful to people concealing very practical crimes.

Who was the killer in The Oblong Murders? (spoiler)

Claire Powell

Claire disconnected the Lamberts' boat gas and phoned Carolyn to trigger the explosion after their secret loan was called in. She then killed witness Max Fuller and Freddie Raft when the promissory note resurfaced; her attempt to kill Barnaby, Jones and Paddy in a second gas explosion failed because the bottle was empty.

Verified motive

Claire killed the Lamberts rather than repay the secret £85,000 loan that had financed the pub and sustained the life she and Paddy presented. She killed Max because he was the contract's surviving witness and Freddie after Freddie used the rediscovered promissory note to demand help, trying to destroy every route to the debt and the original murders.

Verified important clue

Archive case 85 · checked 16 September 2026The promissory note recovered from the Lamberts' laptop

The digital document records the concealed loan that funded the pub and names Max Fuller as its witness; Max's murder on the night of the boat explosion and the resurfacing note connect Claire to the Lamberts' deaths, Freddie's discovery and the later gas trap without treating Lucy's infiltration as part of the killings.

Verified decisive clue
