    Murder on the Meridian

    murder
    hard
    ≈ 60 min
    Date opened

    Friday 10 October 2025

    Lead investigator

    DI Ros Calder — Aviation Liaison, Metropolitan Police

    Location

    Meridian Airways MM018, business cabin, suite 2A (LHR → Singapore)

    Subject

    Julian Thorne, 58 — Founder & Chairman, Thorne Hospitality Group

    Incident summary

    On the overnight flight MM018 (departed Heathrow 21:50, Thu 9 Oct), Mr Thorne was found unresponsive in his reclined business-class suite during the 05:10 pre-descent welfare check and could not be revived. He had a documented severe tree-nut allergy; an emptied adrenaline auto-injector was found in his suite and the initial impression was a fatal accidental allergic reaction. The aircraft was met at Singapore; the body was repatriated and a UK post-mortem flagged the death as suspicious. The cabin carried no cameras — but the aircraft's systems logged almost everything else.

    Your objective

    Establish whether Mr Thorne's death was an accident or an unlawful killing; if unlawful, use the aircraft's records to find who could have reached his suite during the night window, eliminate the rest, prove how and why, and name the responsible person with supporting evidence. Each stage is sealed — you'll need to prove your reasoning to unlock the next.
