Foreign office cipher expert, John Graham, is completely devastated by the death of his pregnant wife, deliberately knocked down in a hit-and-run incident. Driven by a single-minded obsession, he tracks down one of the killers, and repeats the same horrific incident that killed his wife. The only clue left at the scene of the crime is a note written in code, which leaves the police mystified. An unconnected enquiry has led to the arrest of the other killer of Graham?s wife. Whilst on route to prison, Graham abducts her and brutally repeats the same execution. Has Graham got away with his revenge, or will the coded letter lead the authorities to him?
