Daily Mail : A secret stalker. Witnesses who won't talk... but the most tantalising question of all is... Who's got the spy-in-the-bag's missing laptop?

A secret stalker. Witnesses who won't talk... but the most tantalising question of all is... Who's got the spy-in-the-bag's missing laptop?

Number 36 Alderney Street stands in a terrace of tall white houses with gleaming door knockers at the heart of a London enclave the posh estate agents call ‘alpha territory’.

The Queen’s cousin lives down the road of million-pound homes and for 30 years Mimmo d’Ischia, a nearby Italian eaterie, has been a favourite of the Duchess of Cornwall and film stars Joan Collins and Anthony Hopkins.

Even this week, after the strange murder at Number 36 of young British spy Gareth Williams, there is little to show much has changed.

Nothing, that is, apart from the frantic comings and goings by men in suits from the British secret service, MI6, and detectives from Scotland Yard.

The house is where the decomposing body of Mr Williams, padlocked into a sports holdall and thrown into the bath of his top-floor flat, was discovered by police at 6.30 on the evening of Monday, August 23.

The maths genius, loner and cycling fanatic had not turned up for work as a cipher and codes expert at the headquarters of MI6, half a mile from Alderney Street, on the banks of the Thames at Vauxhall.

Today, the mystery over his death is deepening. Was he killed because of his professional life or his private one? Was it an impromptu killing or one that was planned?

Did he die in the top-floor flat after letting in his own killer? Or was he murdered elsewhere by someone who stole his flat keys, before carrying him back and dumping him?

Is it possible that despite his reputation for clean living, an aspect of his private life has led the young spy into danger? Scotland Yard has not ruled out that a woman, or indeed a man, may have been at his flat in the hours before his death. Was she or he invited there to play a sex game that went wrong?

It is, of course, just another question that needs to be answered about the spy who was ‘on loan’ to MI6 from UK Government Communications Headquarters (GCHQ), the country’s top-secret listening post in Cheltenham, Gloucestershire.

When Mr Williams’s gruesome death first became public knowledge, there were lurid and unproven rumours about his private affairs.

Speculation that ‘bondage equipment and gay paraphernalia’ had been found at the flat was later dismissed as ‘garbage’ by Scotland Yard.

His parents, Ian and Ellen, who live in a bungalow in Holyhead, Anglesey, were horrified at the unsavoury claims about their bachelor son’s supposedly wild homosexual lifestyle.

The family insist he lived an exemplary existence and was not gay. A friend of Mr Williams said that the spy was ‘asexual’, and showed little interest in having a relationship with a man or a woman.

A first post-mortem failed to find the cause of his death. A second examination of his body took place a few days ago to unravel if he was drugged, poisoned or smothered. The results of this are still being analysed.

Yet, in a worrying twist, the Mail understands that a turf war has broken out between the police and MI6, with some police officers ­complaining that the spooks are ­hindering their investigation into the spy’s death.

The Mail has learned from sources close to the investigation that Mr Williams informed MI6 that he believed he was being followed in the months before his death, though murder squad detectives say they have not been told this.

This suggests that every aspect of his life at work and at home should be put under the microscope. However, there is frustration at Scotland Yard that the ‘security concerns’ of MI6 are stopping this wide-sweep inquiry happening.

Police attempts to quiz two spies still working at GCHQ who knew Mr Williams well have been unsuccessful and some detectives suspect they have been ‘blocked’ by both MI6 and GCHQ. It is also understood the murder squad was unable to get to one of his closest friends, a former GCHQ spy.

The man lived at the Alderney Street safe house in 2005 and visited there earlier this year. ‘He knows the day-to-day movements of Mr Williams and that is why he is important,’ added our source.

Scotland Yard murder detectives were this week also waiting to quiz another former GCHQ employee, who suddenly moved to America from Cheltenham six weeks ago and is said to be a ‘best friend’ of the dead codebreaker.

There is also friction between MI6 and GCHQ over the level of protection given to Mr Williams while on his London secondment. ‘Some people feel that he was sent to MI6 on secondment as a goodwill gesture and the intelligence service then “lost” GCHQ’s man,’ said a source.

It is a troubling backdrop to any major murder investigation, especially one into an expert codebreaker who was playing a significant role in protecting Britain.

Meanwhile, the Mail has learned of intriguing riddles about his death. The spy’s brain showed no signs of bruising, indicating he was not knocked unconscious before he died.

This has led to speculation that he may have been killed with a tiny injection of poison, possibly through his inner ear. If so, the needle mark would be almost invisible to the naked eye.

Another riddle is that Mr Williams’s personal computer is thought to be missing. He had designed the small machine to his own specifications and it ‘cannot be found’, the Mail has been told.

The laptop, which Scotland Yard refuses to officially confirm is missing, is crucial to the investigation. It could be a vital window on Mr Williams’s private life, his innermost thoughts, any transfers to and from his online bank account and would reveal if he had money problems.

Importantly, it will help trace his movements between the time he was last seen alive, on August 15, and the discovery of his body eight days later in his flat, where there was no sign of a break-in.

This will help pinpoint the time of his death, which is essential to finding a killer. Mr Williams’s bank and credit cards were used during these crucial eight days.

Troublingly, because it is not known when he died, it has been impossible to discover if they were used by him, or someone who had stolen them from him and was involved in his murder.

In a further conundrum, one of the first police officers who entered the flat after Mr Williams was ­discovered dead saw some white powder on several surfaces in the kitchen and living room. Although this could prove innocent, the ­powder is being tested in case it is cocaine or another drug.

In particular, some Scotland Yard detectives believe a public appeal for sightings of Mr Williams in the missing days before his death is essential to solve the murder mystery.

It would involve the release of more photographs and details about his lifestyle, but it is understood to have been ruled out by MI6, which is worried that terrorists might use the information to identify other British spies and their own secrets.

It all sounds disturbingly similar to the case of 28-year-old journalist Jonathan Moyle, another British intelligence agent, whose body was found hanging inside a hotel wardrobe in the Chilean capital Santiago in 1990 with a padded noose around his neck.

He had been investigating a company — ostensibly for his British defence magazine — which was modifying helicopters, possibly to carry nuclear weapons, to sell to the Iraqi dictator Saddam Hussein.

But his friends and family believe security sources planted the ­suggestion that he had died while engaged in an auto-erotic act and tried to stand in the way of the family’s own inquiries.

It took his outraged father to expose the cover-up — and find out that his son had been drugged, ­suffocated, injected with a lethal substance and then strung up in the wardrobe, a view supported by the British coroner, who returned a verdict of unlawful killing at his inquest eight years later.

This week, the Mail traced Mr Moyle’s former fiancée Annette Kissenbeck to her home in Germany, where she said the latest death of a British ‘spy in a bag’ brings back painful memories.

‘The British intelligence services tried to smear Jonathan by suggesting he was sexually deviant,’ she said. ‘I felt so helpless and alone trying to stand up to what was untrue against such powerful and shadowy forces.’.

The rumour that Moyle indulged in auto-erotic experiences first ­surfaced at a British embassy cocktail party attended by journalists in Santiago, adding weight to the Chilean claim that he had died by his own hand.

Annette says both were smears to cover up the truth about the murder and the illicit trade with Iraq. ‘Jonathan had everything to live for. We were totally in love with each other and about to get ­married,’ said Annette this week at her home in Essen, where she works as one of Germany’s leading child doctors.

A year after his death, a Chilean judicial investigation concluded that Moyle had been murdered. But two years later, in 1993, the murder investigation was wrapped up without a single suspect being arrested.

‘Jonathan just wasn’t the type to be depressed. And never in all the time we were together was there any hint that he was into auto-erotic sex,’ said Annette this week.

Even today, she is convinced that the spread of false information was deliberately orchestrated by shadowy figures in British secret services to cover up their own knowledge of the helicopter sales and to protect the UK’s relationship with Chile.

So could the extraordinary story of Jonathan Moyle shed any light on the death of Gareth Williams?

Williams played a key role in the world’s most sensitive and ­secretive electronic intelligence-gathering system.

He was helping to oversee a network called Echelon. It links ­satellites and super computers in Britain and the nations of our Western allies, including the U.S.

Set up to monitor the military and diplomatic communications of the Soviet Union during the Cold War, Echelon now eavesdrops on terrorists, such as the Taliban in Afghanistan, threatening British security.

In particular, it listens for key words and phrases that might ­suggest that an attack on this country is being planned by overseas terrorist cells or home-grown subversives.

He was signed up by GCHQ at 21 while studying for a post-graduate maths certificate at Cambridge, a favourite recruiting ground for the secret services.

His career path was meteoric. Williams had two passports, which allowed him to travel incognito if necessary. Soon he was working for long spells in Afghanistan for our secret services.

Four times a year, he paid visits to America to liaise with the powerful National Security Agency in Fort Meade in Maryland.

When he died, he was living rent-free at Alderney Street, which was bought by MI6 as a ‘safe house’ ten years ago.

It is one of many owned by MI6 dotted around Pimlico, which have been swept for listening devices and kept under surveillance. They are used to put up visiting operatives or to conduct de-briefings in total secrecy.

Mr Williams was due to return to his former flat, rented from a landlady, in Cheltenham yesterday and start back at work at GCHQ later this month.

An associate of Mr Williams told the Mail this week: ‘Gareth really didn’t like London, although he was sent on secondment to MI6 more than once.

‘He suffered it because he had to for his career. He did make a few friends, mainly others sent from GCHQ in Cheltenham who also lived at this MI6 place in Alderney Street.

‘They are the people that know the most about how he spent his spare time over the past few months and MI6 must let the police murder squad speak to them.’

So will the truth about death of the young spy Gareth Williams ever come to light amid the smears and secrecy of the murky world of espionage?

Today, almost a fortnight after the tragic discovery at 36 Alderney Street, you wouldn’t be wise to put money on it. Even if your name was James Bond or George Smiley.
