Firstly the location of Johnoes house was in North End Road Golders Green Green.It stars one of my favourite actors in Nigel Patrick and villains in Darren Nesbitt.I saw the film at the Odeon Temple Fortune on 24th November 1964.I would make the point that so many detectives at Scotland Yard at the time were corrupt they didn't need to frame them.I enjoyed the film then and now with reservations as I felt ,and still do that the climax is very contrived.By the performances of the dog and cat were noteworthy!
