Shadow of a Man (1955)

Much better than your average fayre, this one. After an altercation in a nightclub; a drunk (Bill Nagy) is found dead. Initially the coroner says it was a heart attack, but neither the police nor his old friend "Landers" (Paul Carpenter) are satisfied and along with his widow (Rona Anderson) they try to get to the bottom of it. There are a couple of sub-plots to this and the photography in/around the English seaside resort of Hastings provides for quite an interesting look at 50s Britain (and their habit of holidaying in great numbers where there is a pier!).
