  • Family visit
  • Quiet suspicion
Break the seal: reveal the finding

The pattern of deaths is real, and its motive lies in control of money and the vulnerability of residents whose testimony is dismissed.

Verified killer

Pru Bennett

Pru smothered her terminally ill aunt Celia Armstrong in what the resolution presents as a mercy killing. The other three suspicious nursing-home deaths were natural and are not attributed to Pru or the staff.

Verified motive

Pru acted to spare Celia the slow, painful and undignified death expected from her terminal cancer; the resolution presents this as a mercy killing, not a motive shared by the home's other natural deaths.

Verified important clue

Archive case 11 · checked 16 September 2026Celia Armstrong's terminal-cancer diagnosis

The diagnosis gives Pru's account its essential context: Celia's is the one deliberate death at Lawnside, a mercy killing kept separate from the three residents whose deaths remain natural.

Verified decisive clue

Archive case 11 · checked 17 September 2026Pru Bennett's direct confession

Pru explicitly admits that she ended Celia Armstrong's life. Read with Celia's terminal-cancer diagnosis and the medical review of the other residents, the confession isolates one deliberate mercy killing from the three deaths that remain natural.

Verified red herring

Archive case 11 · checked 17 September 2026A serial murderer targeting Lawnside residents

Several residents die close together and concern inside the home suggests that one offender may be killing elderly patients. Medical review leaves the first three deaths natural; only Celia's later death is deliberate, and Pru explains it as a separate mercy killing.

Verified death and discovery order

Archive case 11 · checked 16 September 2026
  1. death
    Three residents die naturally

    Mrs Mortimer, Muriel Harrap and Madge Fielding die at Lawnside, but the investigation does not establish murder in any of those cases.

  2. discovery
    The earlier deaths are reviewed

    Concern inside the home brings the three deaths under scrutiny before the inquiry distinguishes them from Celia's case.

  3. death
    Celia Armstrong is smothered

    Pru Bennett ends her terminally ill aunt's life to spare her the painful and undignified death expected from cancer.

  4. discovery
    Pru explains the mercy killing

    Celia's overnight death and Pru's account establish one deliberate death while leaving the other three classified as natural.
