Was Gareth Williams a victim of his own private life, or a targeted hit by a foreign intelligence agency? This episode navigates the two warring theories that define this cold case. On one side, the official police conclusion of a "solitary accident" involving claustrophilia; on the other, the coroner's verdict of "unlawful killing" potentially linked to Williams's work on Russian money laundering. We re-examine the timeline of his final days, the £25,000 of unworn designer women's clothing in his closet, and the suspicious "redirection" of the investigation that some say points to an MI6 cover-up.
