Released in the UK as the support short to Dead & Buried (1981), initially in fifty screens in the ABC network in the North-East of England, later in the rest of the country.
During the film, there is a radio news broadcast and among the news stories mentioned is one that says that "the UK's first Polaris submarine will be launched today" and this event took place on Thursday 15th September 1966. This suggests that the cricket match and the murder took place on Sunday 11th September, as cricket matches at club level are not played on working days. The broadcast also states that the woman was reported missing on Tuesday, presumably 13th September, which fits in neatly with the other likely dates.
