Murder at the Gallop (1963)

Miss Marple, amateur sleuth/professional busybody, thinks there's something fishy about the death of an acquaintance and sets about trying to figure out what it is -- dragging along her faithful sidekick Stringer.

Margaret Rutherford sparkles in the title role. The way she holds her face in an exaggerated "oh, aren't I clever" expression while waiting for those around her to catch up is comical without being over-the-top. The supporting cast of suspects are a load of fun, as is the inspector on the case he's not even sure is a case.

Lightweight fun.
