Gareth Williams was only 31 years old when he was found naked and decomposing in the bathtub of his Pimlico apartment. His body was inside a red sports bag, zipped shut from the outside and padlocked. No fingerprints were found on the apartment, the bag, or the lock, naturally. Police also found no signs of struggle. The key was inside the bag.

It’s worth reminding that Williams possessed exceptional intelligence and had already achieved success as a cryptographer and mathematician in his short life. His work for MI6, the British intelligence agency, and GCHQ, the government’s communications headquarters, only added to the aura of mystery surrounding the spy’s life and death.

However, the latest forensic examination by Scotland Yard has not yielded any breakthroughs. It did, however, confirm the main theory: Williams most likely was alone at the time of his death. The absence of new DNA on crucial items such as the bag, lock, and bathtub supported this conclusion. To test the proposed scenario – that Williams himself (for some reason) climbed into the holdall and locked it from the outside – rescue expert Peter Faulding attempted the same over 300 times. Yet, each time, he failed. “Not even Houdini would have been able to pull it off,” he stated.

It appears that the investigation has reached its limit. The case of Gareth Williams’ death remains unsolved. Retired Chief Superintendent Hamish Campbell, who led the investigation, continues to insist that the spy’s death may lie in the details of his personal life. Gareth frequented bondage and fetish clubs, searched the internet for information on sexual practices… In short, he led a double life, which may have led to his untimely demise. As far as the police know, at the time of his death, Williams was not in a relationship, although six boxes of unworn designer women’s clothing worth over £20,000 and an orange wig were found in his apartment.

However, Campbell’s theory leaves many questions unanswered. If Williams’ death truly resulted from a tragic accident during an intimate encounter, why stage it with a carefully thought-out holdall? The theory of covert games by foreign intelligence services also has its flaws: why target only a junior analyst? Although, to give credit, Gareth was engaged in dangerous work: tracking international money laundering routes of organised crime groups.

Either way, from this point on, Scotland Yard no longer plans to spend time and resources on investigating the death of the MI6 spy. The case remains unsolved but shelved. And in the absence of definitive answers, the public is left to ponder the mysteries surrounding Gareth Williams’ death.
