The Effect
August 2010 in one of London’s most affluent neighbourhoods: Pimlico. It’s the kind of upmarket city district where people keep to themselves, making it an ideal location for someone like Gareth Williams. By all accounts, Gareth is a quiet, intensely private, and intellectually brilliant 31-year-old man. He is an accomplished mathematician, and also a signals intelligence officer for GCHQ – or Government Communications Headquarters – on a three-year secondment to the Secret Intelligence Service, MI6. He is, in short, a codebreaker and spy.
But Gareth’s life and promising career are about to be cut tragically short.
On Monday 23rd August, when Gareth fails to show up for work, his colleagues become concerned. This is highly out of character for the usually reliable and disciplined mathematician. After several days of missed appointments and unanswered calls, they decide to report his absence to the police. Police are consequently dispatched to his top-floor flat on Alderney Street. Finding the door locked and getting no response, they decide to force entry.
Inside, Gareth’s flat is tidy. There are no signs of a disturbance or robbery, no overturned furniture, and no evidence of a struggle. But in the bathroom, police discover an object that will ignite one of the most bizarre and unsettling mysteries in modern British history. Sitting in the middle of the clean and otherwise empty bathtub is a large, red holdall. The zip has been pulled shut, and its two toggles are held together by a small metal padlock. It has clearly been locked from the outside.
With a growing sense of dread, officers carefully cut the bag open, and make a horrific discovery. Inside, folded into the foetal position, is the naked and decomposing body of Gareth Williams. The discovery immediately raises a series of baffling questions. How could a man end up inside a sports bag, zipped and padlocked from the outside? The puzzle deepens when investigators discover that the keys to that very padlock are also inside the bag, lying underneath Gareth’s body.
The scene is a paradox. In addition to there being no sign of forced entry into the flat, no fingerprints belonging to anyone else are found on the bag, the padlock, or the sides of the bathtub. To confuse matters further, Gareth’s own DNA isn’t on the padlock, either. Forensic examination of his body is hampered by decomposition, but it reveals no obvious signs of a violent struggle. Toxicology tests find no common poisons, and there is no evidence he was under the influence of alcohol or drugs when he died.
Since the post-mortem does not seem to clear up any of the mystery surrounding Gareth Williams’s death, the police investigation begins to delve into his private life. It is apparently revealed that Gareth owned thousands of pounds worth of designer women’s clothing, and had previously visited bondage and fetish websites. However, this line of enquiry, too, leads nowhere concrete and the central, physical impossibility remains: just how did Gareth Williams come to be locked inside that bag? Was it a solo act, a tragic accident, even some kind of failed feat of escapology? Or was Gareth’s death actually a murder, an assasination? Did it betray the chillingly clean and professional signature of a secret intelligence agency, an agency which left behind it one of the most disturbing locked-room mysteries of the twenty-first century?
