Arthur Wakesfield surprises a burglar and tries to scare him off, but gets a heart attack from which he later dies in the process. The burglar, John Tinniswood, hardly fares any better, when he comes home because his wife nearly tears his head off, but she still gives him a false alibi when he is arrested for the crime. Wakefield's widow is sure it was him though and starts to follow him around anywhere he goes. Special constable Hector Cowley poses problems of another kind. He is overly officious and a pain in the neck to everybody from sergeant Blaketon and down. And to a lot of other people for that matter. Cowley counts on winning a prize for his gooseberries at the local fair, but somebody destroys them on the night before.
