Examination of UK locations, their use as filming sites in feature films, and the nostalgia of the old films, is a very strong hook.

Original film scenes, the “grabs”; and “now” shots from the web-site reel streets are evidence of these real streets being used by a variety of film producers, directors, and, a killer.

The search for the real streets, the archive material, reveals items of local interest, and in the first 20/30 films, appear notices of  teenage girls going missing. No deaths noted, and no bodies found. Police, of various forces, “continue with their enquiries”. The mystery commences.

Action moves across the midlands and northern England, tracing original filming locations, and, strangely, another missing girl is reported.

The screenplay is not a thriller, no cliff-hanging, no shootings, no car chases and no hero, just a late middle-aged, puzzled, investigator who, through perseverance, or even, obsession, with film locations, keeps stumbling on evidence of missing, young women, in the areas where the films were being made.

He starts collecting film crew details, a similarity of names begins to emerge, pseudonyms, perhaps for tax or even artistic purposes. Location photos show the crews in action, and a distinctive vehicle appears in the background a couple of times.

Back to London, architectural detail, film sites, dozens of films made in the metropolis, and a half-remembered secondary use of a location in Hammersmith, strange, because so far, no ordinary sites, in the hundred or so researched, had ever been duplicated in a feature film.

But Night and the City, used a Hammersmith corner, which had appeared before, in another film, but which one? Associations to pop-music, radio and TV shows and world events create historical atmosphere. Then up came the Case of the Gravesend Arm, an unexplained limb, never identified and never claimed. Long Memorywas made in Gravesend. A curiosity which led our investigator into details of Donald Hume, murderer, and Edgar Lustgarten, crime-series producer, and also evidence attributed to Staffen, Christie and Ruxton, murderers.

Investigation into deviant behaviour, the differences between loners, sociopaths and psychopaths, and their reasons, and up pops the same car again.

The Man Who Never Was, used the Hammersmith site, the second film, no, the third film, using this location, the first use was still unrecalled.

Eire, and examination of films being made in that country. B—J—, was in the crew, a dogsbody, and was listed in the crew in the north of England, when Tread Softly Stranger was being made. And now another girl, an Irish girl, was reported as missing.

Macclesfield was visited and  So Well Remembered was made in that town, and another teenager was lost nearby.

“Dogsbody”, lived in Hammersmith, with, at one time, his sister and mother, and he seems to have worked with almost all the London studios. He’s our perp. He’s dead, but the coincidences continue. The way in which he might have disposed of the bodies is not for the squeamish. His mementos of his appalling crimes has never ever previously been recorded for any psychopathic serial killer.

Both Gyyneth Paltrow, Tom Wilkinson and Ewan Macgregor all appear in recent films which are part of the on-going investigation into the Cinema of Darkness.
