Here is the plot, man and wife appear to have an idyllic marriage, in the book apparently the stress is on what a good man Bob is, unfortunately in the film he comes across as smarmy and creepy but not in a horror type creepy. He turns out to be a rapist serial killer and the wife finds out, to keep the good name and protect the children she carries on with the marriage until she kills him by pushing him downstairs and then suffocating him. Would an autopsy not find the cause of death? an ex detective discovers their secret by combining their names Bob and Darcy which is bedee ??????????? never mind. That is the film no twists, no horror, no tension, acting passable but this is a film which goes out of its way not to alarm the audience, no loud noises, no sudden movements, no gore, no horror, nothing, luckily it was free on Sky so I have only been robbed of my time.
