He proved to be a master of smoke and mirrors playing the insufferable MI5 agent Spider Webb in the Apple TV+ series Slow Horses.
Now actor Freddie Fox, who is a member of the famous acting dynasty, has demonstrated that he is equally adept at maintaining the low profile of a spy.
Freddie, 35, the son of veteran actors Edward Fox and Joanna David, and younger brother of Silent Witness star Emilia, has been dating Sex Education star Tanya Reynolds for almost four years.
Yet apart from an appearance on the red carpet, when they were promoting the 17th Century period drama Fanny Lye Deliver’d, in which they both starred, they have not been snapped together in public.

Now they have gone public for the first time, walking hand-in-hand in Chelsea, south-west London. Wrapped up against the cold, they look almost unrecognisable from their polished appearance at the film premiere, right.
Freddie and Tanya, 32, met on the set of Fanny Lye Deliver’d and the pair, who played young couple Thomas Ashbury and Rebecca Henshaw are believed to have isolated together at his London home during the Coronavirus pandemic. Both actors have a history of playing real characters.
Tanya, named a Screen International Star of Tomorrow, played Queen Victoria in the NBC/Universal series Dodger alongside Christopher Eccleston and David Threlfall.

And Freddie, who previously dated Pride & Prejudice actress Tamzin Merchant, played Marilyn in the Boy George biopic Worried About The Boy, and Margaret Thatcher’s son Mark in the acclaimed Netflix series The Crown.
He once claimed he would never put a label on his sexuality, saying: ‘I wouldn’t wish to go ‘I am this or I am that’ because at some time in my life, yes, I’ve had girlfriends, but I might fall in love with a man.
‘I would hope to say that I am the type of person that would fall in love with people as opposed to sexes necessarily, although the majority of my life to date has been as a straight man.’
Now maybe he is a real-life master of disguise.
