From today’s emails:

    Hi, I have a query….Hope you may be able to help me out… On which Edgar Wallace story / novel was the 1960 Vernon Sewell movie The Man in the Back Seat based? I would appreciate any responses. Thanks. Regards, Ashish Pandey.

Me again:

    No online resource seems to say. Or to clarify, Edgar Wallace is always given as the author, but the name of the specific short story or novel the 1961 film’s based on is never stated. It was part of a series of 46 films entitled The Edgar Wallace Mysteries produced by Merton Park Productions.

    From http://www.britmovie.co.uk/, here’s a list of the cast members along with the longest recap of the storyline that I’ve found anywhere, in case anyone recognizes it. The director was Vernon Sewell. And believe it or not, I’ve even found a photo from the film that I can show you, but — nothing more re Wallace.

   Derren Nesbitt – Tony
   Keith Faulkner – Frank
   Carol White – Jean
   Harry Locke – Joe Carter

Plot Synopsis

EDGAR WALLACE The Man in the Back Seat

   Taut B-movie adapted from an Edgar Wallace mystery with an intriguing premise that’s ingeniously executed by director Vernon Sewell. Sewell outdoes himself with this well-plotted and haunting story of two incompetent crooks and an unwanted passenger which obviously has its roots in the Banquo’s ghost segment of Macbeth.

   Two youthful crooks, cold-hearted Tony (Darren Nesbitt) and his compliant best mate Frank (Keith Faulkner), try to rob bookie Joe Carter (Harry Locke) as he is leaving the dog track with his daily winnings. Unfortunately, the two discover that he’s chained the case to his wrist and consequently they are forced to take him along with them as they try to find a way to salvage the money. They drive through the London night looking for an opportunity to break the chain but wind up back at Frank’s house – much to the chagrin of his nagging wife Jean (Carol White). Having beaten the bookie unconscious, the pair douse him in alcohol and dump him near a hospital in the expectation of a passer-by discovering him, but the pair have to retrieve the lifeless bookie when they realise they’ve left fingerprints behind. They return to Jean’s with the body, where a neighbouring back-street doctor declares the bookie practically dead, Tony and Frank drive north to Birmingham to dispose of the body, but on the North Circular the pair encounter a eerie experience.
