Hearsay rule

The Hearsay rule marks the boundary between what an investigator may learn from another person and what can be presented in court as testimony. In the inquiry into Katy Devlin’s death, Rob Ryan applies it when Rosalind Devlin begins to report what Jessica Devlin told her: the account may matter to the investigation, but Ryan says he needs to hear it from Jessica herself because Rosalind’s version would be inadmissible hearsay.

Definition and Application

At the point the rule is invoked, Rosalind is trying to convey Jessica’s account of having seen Katy. Ryan interrupts to insist that Jessica must speak directly to him; a statement repeated by Rosalind cannot stand in court as Jessica’s evidence. The scene presents the rule through a practical distinction between the original speaker and the person recounting her words, rather than through a general explanation of legal doctrine.

The Question of Jessica’s Account

The exchange is especially charged because Jessica has already made a brief, direct disclosure during an earlier conversation: she says that a man frightened Katy. When Ryan later asks what she saw, Jessica does not answer. Rosalind then steps in, saying that Jessica told her she saw Katy, but Ryan refuses to treat the relayed account as a substitute for hearing from Jessica.

Direct Testimony and Withdrawal

Once Ryan asks for Jessica’s own account, Rosalind encourages her to speak, addressing her gently and emphasizing that it is important. Jessica turns away and whispers that she does not remember. The rule therefore does more than interrupt Rosalind’s narration: it exposes the gap between a claim that may have been shared privately and evidence Jessica is able or willing to give directly. The scene leaves the information unresolved rather than allowing Rosalind’s certainty to settle what Jessica saw.

Place in the Investigation

The episode distinguishes a useful investigative lead from testimony that Ryan says can be admitted in court. It also sits alongside the inquiry’s reliance on material findings: investigators consider blood typing, a possible weapon recovered near a wall, and evidence connected with a missing archaeological trowel. Those clues require interpretation, while Jessica’s account raises a separate question about who can properly speak to what she witnessed. The rule thus becomes part of the investigation’s larger struggle to establish what happened without allowing one person’s account of another’s experience to stand in for the witness herself.
