Marble Hall Murders, Episode 4

Susan wakes from a nightmare to learn that Eliot is in a coma after the hit-and-run. Blakeney and Wardlaw question her about the party and inspect her car. Damage to its front and material caught in the grille make her a suspect, despite her insistence that she travelled by train.

Harrison Carter tells Pünd that an antiquity at Villa Belmar was stolen during the war. Maria alerted him to it, and Robert brought him into the house to confront Elmer. Pünd connects the confrontation with the villa’s open windows: Lady Chalfont could have overheard it. The question becomes whether this explains her anxiety about her husband.

Susan speaks to Edward and encounters Roland at Eliot’s house. Roland’s easy access leads her to identify him as Gillian’s lover. Elsewhere, Matthew admits that his publishing interests include a new Tiny People book and that the arrangement with Susan was intended to help manage Eliot. Susan asks Elaine to arrange a prison visit to Charles Clover.

In Corfu, Sofia’s disappearance becomes a second murder investigation when her body is found. Her supposed engagement, access to the will and possession of Harry’s photograph draw Pünd’s attention. Family members offer accounts of Harry’s movements, but those accounts still need to be tested.

The ending breaks the visual rules of the story. Pünd and Vassilikos leave the villa and find themselves surrounded by emptiness: Eliot has died and the manuscript stops. It is an unusually direct expression of their dependence on a writer. Susan has lost a person she was trying to help; Pünd has lost the pages through which he could finish his case.

For Pünd, the stolen object supplies a possible explanation for Lady Chalfont’s wish to speak privately. Discovering an objectionable truth about a husband could change a marriage and the future of an inheritance. It still has to be connected to the poisoning, rather than treated as a complete answer by itself. Sofia’s work for the lawyer makes her different from a casual visitor: she has access to information that other people at the villa may want. Her disappearance therefore changes the investigation’s urgency as well as its list of possible motives. Susan’s discovery about Roland similarly changes the meaning of an ordinary domestic detail. Access to a house can disclose a relationship, not simply a route for a criminal. Matthew’s admission then forces her to reinterpret the editing commission. What she accepted as help for an author has also served other people’s business interests. When the manuscript ends, the television image makes the resulting loss of control visible: even the detective cannot continue beyond the words available to him.

• The largest change is geographical. The novel sends Pünd to southern France. Television places this case in Corfu. That gives the villa and its surroundings a different look.
• Both versions use a continuation novel called Pünd’s Last Case. Eliot takes responsibility for another writer’s detective. Susan brings editorial experience from Alan Conway’s earlier books.
• An actor can appear in both worlds. That makes the connections visible on screen. Distinguish a casting choice from a plot change. Recognising an actor does not prove Eliot’s portrayal is accurate.
