One of Ray Adams' colleagues at NDS, during the company's worldwide pay-TV hacking campaign (circa 1997 to 2002) was Reuven Hasak, former deputy chairman of the Israeli Security Service, the Shin Bet. (Mr Adams was head of criminal intelligence at the Metropolitan Police Service, which makes them close colleagues even before they took the Murdoch shilling, assuming that Mr Murdoch was not paying them anything while they were both on the public payroll, which does seem to be an assumption that Surrey Police at least are willing to question!)
There's apparently a law against publishing photographs of Israeli intelligence chiefs. So here's an oil painting, of the three founding directors of an Israeli security consultancy, including Reuvan Hasak, Medawar assumes that Mr Hasak is front centre, but would be interested if anyone is able to offer (possibly anonymous) correction.
Residents of Alderney Street, or friends and colleagues of Mr Gareth Williams, might want to scrutinize this magnificent group portrait and see if it jogs their memory at all.
