In the 1950s Yorkshire, Betty Stevenson, a married mother of one, falls in love with her Polish neighbour, Alex Crazenovski, aka "Craze."
She responds in kind, and her letter is found by Craze's pregnant wife, who promptly seeks him out at the fairground where he works and shoots him dead.
[2] Kay Mellor was inspired to write the story after her mother confessed to having an affair with a Polish neighbour in the 1950s when living in a poorer area of Leeds.
[3] Just like the story, the unnamed Pole was killed, which ended her mother's affair which she had kept secret for 30 years before revealing all.
Mellor admitted that the film rights had been mooted, but she feared the production would end up with "...Cher on a rooftop in Detroit".
