Episode Details

In August 2010, the body of MI6 codebreaker Gareth Williams was found inside a padlocked North Face bag in his London bathtub. The mystery isn't just who killed him, but how the scene remained so impossibly clean. This episode dissects the forensic contradictions that have baffled Scotland Yard for over a decade: the absence of fingerprints on the padlock, the keys found beneath his body, and the "sauna-like" heat in the flat that accelerated decomposition. We ask the ultimate forensic question: Can a human being truly lock themselves into a bag from the outside, or was this the work of a "clean team" capable of erasing every trace of a struggle?
