Who Was Maddox? (1964)

I'm inserting reviews for films I'v seen that currently lack one, so here goes... Edgar Wallace mystery, not one of the better ones, involves blackmail & murder, fair. Not the most comprehensive of reviews it's true, but I saw it on itv 25th Jul 1983; and would probably have forgotten it a week later not to mind 32 years. The Director made only one other feature, another E.Wallace entry Accidental Death (1963), The only cast names I recognize are Finlay Currie and Bernard Lee; It's a fairly obscure title, there is no official DVD release, but hopefully someone will track it down and write a more informed review.
