This is what a movie franchise was like in the context of early-60s British cinema. It's cursory, pedestrian and touch too self-amused. It may have been great fun for fans at the time to see Miss Marple reduced to dancing a frug, but that's not the route to timeless moviemaking. The film does contain a nice throwaway performance by Katya Douglas as one of the heirs of the poor victim whose untimely end triggers the murder mystery. She plays her scenes with an amusing casual sense of entitlement.
