On 4th April 1962 James Hanratty was hanged for an apparently motiveless shooting of two lovers on the A6 main road near London. But much of the evidence had been circumstantial, and pointed equally well towards another name, Peter Alphon. When he confessed during an interview that he had carried out the murder many people were amazed that no charges were ever brought and controversy still rages as to whether Hanratty was wrongly executed.
