With its gabled , late-Victorian red-brick exterior and oak-panelled interior , Cournswood House could almost be Bletchley Park , the English country house at the heart of the recent Oscar-nominated drama The Imitation Game , about the cracking of Germany 's wartime Enigma code . So it is appropriate that at least two of Cournswood 's long-term residents have had strong Bletchley connections . The first was wartime Naval cryptographer and Enigma codebreaker Dillwyn Knox , who bought it in 1921 and lived there until his death in 1943 . His funeral was attended by many from Bletchley Park , and a memorial stone to Knox can be found bordering the property . Cournswood House is in the south of Buckinghamshire – in ten acres of secluded woodlands in the picturesque village of North Dean .

' While both are in Buckinghamshire , Cournswood House is in the south of the county – in ten acres of secluded woodlands in the picturesque village of North Dean – while Bletchley Park is in the town of Bletchley in the north , 20 miles away . During the Second World War at Bletchley Park , Dillwyn Knox led the team that made the first breaks into the code Germany was using , and he encouraged Alan Turing – the subject of The Imitation Game – in his work there . Although Knox does not feature in the new movie , he was portrayed by actor Richard Johnson in the 1996 television film Breaking The Code , which starred Derek Jacobi as Turing and Prunella Scales as his wife Sara . The pool is in a glasshouse , where vines thrive in the heated environment . A separate glasshouse houses the Jacuzzi and a herb garden . Cracking mysteries seems to be something Knox enjoyed in his private life too , as novelist Agatha Christie was a good friend and often visited Cournswood .
