Twisted Nerve

The film opens with views of the school for people with learning difficulties where Pete Durnley lives. Located by Steve Randall, this is in the grounds of Harperbury Hospital on Harper Lane, London Colney in Hertfordshire.

More residents of the school are seen as the camera pans. Steve Randall identifies Harperbury Hospital on Harper Lane in London Colney which closed in 2001. The Kingsley Green mental health facility opened on the site in May 2009.

The camera pans further to reveal Martin Durnley (Hywel Bennett) playing catch with his younger brother Pete (Unnamed). The grounds of Harperbury Hospital in London Colney, Hertfordshire found by Steve Randall.

Susan Harper (Hayley Mills) is suspected of helping Martin to shop lift when he's apprehended by a Store Detective. The tiling reads 'Randall's', whose department store stands on Vine Street in Uxbridge, Middlesex. The shop was also seen in 'Victim'.

The store closed in 2015 and is shortly to be converted to flats and shops. This is the right hand entrance if the screen capture was for the left hand I have a very similar shot for that. (RL)

From a taxi, Martin watches as Susan leaves for her library job with Shashee Kadir (Salmaan Peerzada). Ian Hedgcock identifies this as Cambridge Park in Twickenham.

Ian also provides this proof.

Martin waits for the pair to move on before starting to follow. Cambridge Park located by Ian Hedgcock.

Susan and Shashee turn a corner as Martin trails along in the background. Ian tells us that this is the junction of Richmond Road and Cambridge Park in Twickenham.

John Harwood notes the hedge instead of a wall. (SJ)

Whistling as he walks, Martin keeps his distance. The corner of Richmond Road and Cambridge Park advises Ian.

The same spot now, captured by Ian.

A Man comes out of a telephone box, asking for some change. Richmond Road in Twickenham with St. Stephen's Church in the background located by Ian Hedgcock.

And Ian also provides this comparison, without the prop phone box.

Martin walks on, ignoring the Man. A reverse point of view along Richmond Road, Twickenham found by Ian Hedgcock.

The end of the journey to work. David Dent advises that this is the Library on Treaty Road in Hounslow.

Martin comes to a halt outside the library after Susan enters. The entrance to Hounslow Library on Treaty Road located by David Dent.

A taxi brings Martin to The Excelsior, London Airport Hotel. Bath Road, Heathrow, Middlesex.

The camera pans with the taxi as it comes to a halt at the hotel's entrance. The hotel is now known as Le Meridien Hotel Heathrow.

Martin is sent away after he leaves the hotel and turns up at Susan's house. Subtle differences between this shot and later images suggest that this is a studio set.

Susan calls out and Martin comes to a stand in the rain before returning to the house.

Martin hurries Susan away from the library after work. Hounslow Library, demolished along with the Town Hall and the rest of the street in the mid 1980s to make way for the Treaty Centre. Information from David Dent.

Susan is called over by Philip Harvey (Christian Roberts). Outside Hounslow Library, recognised by David Dent who worked there in the late 1970s.

After accepting a lift, Susan is driven away by Philip. David identifies this as Treaty Road, looking towards High Street in Hounslow, Middlesex.

On another occasion, Philip arrives to call on Susan. Cambridge Park, Twickenham located by Ian Hedgcock.

Without access to the property, John H. opted for a closer shot. (SJ)

Superintendent Dakin (Timothy West) arrives at the house with his men as Susan is held at knifepoint inside. Looking onto Cambridge Park, found by Ian Hedgcock.

Again John took this with his back to the gates. (SJ)
