Why it matters

Barnaby begins the series by challenging a senior officer's tidy conclusion and following the people whom the first inquiry overlooked.

A tramp is killed in woodland after a fox hunt, and retiring Superintendent Ronald Pringle arrests a local poacher. Barnaby returns from holiday unconvinced by the solution and reopens the case when the poacher's father is shot dead.

Pringle's own death adds urgency to an investigation already entangled with the Fitzroy estate, the hunt and relationships that cross class lines. What first looks like the killing of a stranger becomes a case about who belongs to the village and whose family history has been hidden.

Who was the killer in Death of a Stranger? (spoiler)

The deaths are connected by concealed parentage and the effort to preserve a respectable family account; Barnaby's doubt about the first arrest is justified.

Who was the killer in Death of a Stranger? (spoiler)

Grahame Tranter · Marcia Tranter · James Fitzroy

Grahame killed Michael Darrow, Ben Gurdie, Ronald Pringle and Marcia Tranter; his own later death is recorded separately as suicide. The episode also establishes that Marcia and James Fitzroy killed Simon Tranter years earlier.

Verified motive

Marcia and James killed Simon because his sterility would expose her pregnancy by Michael Darrow. Years later Grahame killed Darrow to stop him exposing Grahame's true parentage and inheritance claim, Ben after he caught Grahame searching for the evidence, Pringle after he witnessed Kate's affair, and Marcia after her deception destroyed the two relationships Grahame valued.

Verified important clue

Archive case 10 · checked 16 September 2026The photograph and fingerprints that unmask Michael Darrow

The self-timed photograph, fingerprint match and later DNA result show that the dead stranger was actor Michael Darrow rather than Simon Tranter, exposing Grahame's parentage and endangered inheritance.

Verified decisive clue

Archive case 10 · checked 17 September 2026The DNA result linking Grahame to Michael Darrow

The result proves that Grahame is related to the dead stranger, confirming that the victim was his biological father rather than Simon Tranter. That finding exposes the inheritance threat Grahame had already described and connects his three present-day murders to the evidence he was trying to suppress.

Verified red herring

Archive case 10 · checked 17 September 2026Ben Gurdie's conviction for Michael Darrow's murder

The first investigation treats the local poacher as Darrow's killer and the case appears resolved. Ben's own death and the repeated use of the hounds overturn that account, exposing Grahame Tranter's evidence and the family secret the wrongful conviction concealed.

Verified death and discovery order
