Baffled!

Tom Kovak races in the Pennsylvania 500 Mile Special. Brian Horn advises that this is Oulton Park race circuit near Little Budworth, Cheshire and adds "The film sequences are of the 1971 Gold Cup and this capture shows Henri Pescarolo in a March followed by Peter Gethin and Howden Ganley both in BRM’s".

Brian provides this image of Lodge Corner.

The car is brought into the pits to refuel before Kovak returns to the track where he experiences a vision.

During the vision, the driveway of an English country house appears, causing Kovak to crash the car. Taplow Court on Cliveden Road, Taplow in Buckinghamshire.

David Copley provides this clearer view of the location.

At Denver's Stapleton International Airport, actress Andrea Glenn (Vera Miles) arrives with her daughter Jennifer (Jewel Blanch) in a Cadillac Fleetwood 60 Special cab. Manuel Gurtner explains that the real Stapleton Airport was replaced by the Denver International Airport in 1995 and was completely demolished except for the Control tower. However, this is a London location . . . the lower level of the Thames facing side of the Royal Festival Hall on the South Bank in SE1 recognised by Jonathan Wood.

Looking south-west with a surviving concrete walkway to the right. SJ

Photographers approach before the two continue into the airport to begin their journey to Devon in England. Jonathan Wood points out that the the Royal Festival Hall looks a lot different these days with the addition of various cafes and shops beneath the overhanging terrace.

A new look to "Denver Stapleton Airport." SJ

Arriving in England, Andrea and Jennifer are driven to fictional Wyndham Manor where they are expecting to meet Duncan, their estranged husband and father. Alan Bourke recognised the view as looking down on Widemouth Bay in Devon from the coastal path running between Widemouth beach and Millook to the south.

Spending a week at a favourite holiday haunt in north Cornwall, Malcolm Tinnelly took time to capture the view now, in which the white dishes and spheres of the GCHQ installation are lit up by the sun.

At the house seen in Kovak's vision, the Americans wait for Mrs. Farraday to appear as a Housekeeper and Hopkins the Butler (Ewan Roberts) collect the luggage from the car. Following World War II, Taplow Court was owned by British Telecommunications Research, a subsidiary of Plessey Electronics for over forty years.

The same entrance captured by David Copley.

Having travelled to London to meet psychic researcher and occult expert Michele Brent, Kovak is driven through the City streets by the Englishwoman. Approaching Marble Arch on Bayswater Road with Oxford Street ahead and the corner of Cumberland Place to the left.

Peter's shot proves the location.

On their way to investigate the racing driver's vision, Michele and Kovak make their way to Wyndham Manor. Marble Arch in London W1 with the northern end of Park Lane in the right distance.

More of the same thoroughfare now from Peter.

Kovak is alarmed as Michele negotiates her way through busy traffic. Facing south on Park Lane.

Peter moves on to Park Lane too.

Michele's car carries the two out of London and on to Devon. Looking north on Park Lane W1 with the since demolished Marble Arch Tower on the extreme left.

Bike lane, bus lane, car lane. All rather untidy. SJ

Andrea and Jennifer walk through Wyndham village to call on Louise Sanford who had made the reservation for them at Wyndham Manor. The junction of Dean Lane and Alleyns Lane in Cookham, Berkshire discovered by Steve Randall.

Nearly half a century later, Antony Blair captured the white building known as The Forge.

Mother and daughter arrive at the front gate of Cliff Cottage. Phil Richards recognised this as the junction of Winter Hill and Dean Lane, Cookham. (RL)

Phil couldn't get the same angle exactly as the original shots were taken from the garden of the thatched cottage in the next capture but he managed to get in the same house (now extended) and the verge where the two roads separate. (RL)

Jennifer knocks at the door which is opened by Louise Sanford who had made the booking at the request of Duncan. The junction of Winter Hill and Dean Lane, Cookham in Berkshire as identified by Phil Richards. (RL)

The original cottage has been significantly modified with the thatched roof totally replaced. The hedge would in any event prevented Phil from achieving a true comparative shot so he has provided this wider one to reveal the location as it is now. (RL)

Verelli (Christopher Benjamin) arrives at the house and is introduced to Tom Kovack (Leonard Nimoy) and Michele Brent (Susan Hampshire) by Catherine Farraday (Rachel Roberts). Since 1988 Taplow Court has been a Soka Gakkai International Buddhist centre.

David Copley took advantage of one of the few open days that Taplow Court hosts during the summer months.

As the investigation continues, a taxi brings Michele to the heart of London's theatreland. The Apollo Theatre on Shaftesbury Avenue W1 confirmed by Peter.

More proof from Peter.

Lead to her destination by Mrs. Sanford's remarks at Wyndham, Michele gets out of the cab. Looking west on Shaftesbury Avenue, towards Piccadilly Circus. Location confirmed by Peter.

Peter found Shaftesbury Avenue just as busy.

The camera catches up with Michele as she turns the corner of Tavistock Street and Catherine Street in WC2.

The same corner captured by Peter.

Finding the Stage Door Keeper, Michele asks if anyone in the theatre would know John Parrish. Looking out from the Stage Door of the Novello Theatre to the corner of Tavistock Street and Catherine Street.

Peter recreates the view.

The Stage Door Keeper directs Michele to Parrish's shop on the King's Road. In reality Blackfriars Road SE1 facing south, with Nelson Square on the left. (SR)

Nelson Square is unchanged but the block to the left has been replaced. SJ

The shop is found to be a burnt out ruin, full of discarded occult paraphernalia. This is across the road from the last capture, and is where Southwark tube station was built in 1999. In the background is The Ring public house, which still stands. (SR)

The Ring is well advertised in the background. SJ

With the case eventually solved, Kovak and Michele say their goodbyes. Taplow Court also appears in 'Night of the Eagle', 'The Calendar' and 'What a Carve Up'.

No great change is apparent in David Copley's view.

As the two prepare to part company, another vision has Kovak seeing the story's perpetrator, John Parrish (Mike Murray), at Orly Airport.

Agreeing to team up and head for Paris, Kovak and Michele drive away. Taplow Court on Cliveden Road, Taplow in Buckinghamshire.

David Copley again provides a clearer view.
