This is one of these films that could really have benefitted from a stronger, more charismatic, leading man! As it is, Michael Winner chose to saddle us with the wooden and rather plodding Terence Longdon to play "Kingston". He has arrived in the heart of academic Cambridge to establish just what happened to his brother who was found lying at the foot of his bedroom window. The police have assumed suicide, but he is not convinced. It doesn't take long for him to find himself embroiled in some skulduggery surrounding stolen goods and more bodies! Finally convincing the constabulary - "Insp. Wills" (Donald Gray) - that there is more afoot we embark on a briskly paced mystery as he and "Mary" (Diane Clare) who is the daughter of another seemingly suicidal victim begin to close in on the culprits - and attract their attention too! It's not great this - the acting is pedestrian and there is way too much verbiage, but the story is actually quite decent and the film does not hang about - each scene seamlessly picking up from the previous as if it were a stage play! It's nobody's finest work, but is still not a bad hour's watch.
