Set in Yorkshire in 1979, best friends Sharon and Miv hear information on the news about the Yorkshire Ripper. Miv has a difficult homelife. Her mum has stopped speaking, her dad works all day, and her Aunty Jean has come to stay to help look after the family.
Miv spends a lot of time at Sharon's house. They decide to write a list of all the suspicious people and do their own investigation to try to find the Yorkshire Ripper. They follow people and decide whether or not they could be suspects. The local shopkeeper is on the list for a very short time, but they really like him and he is friendly with them. A lot of people are quite racist towards him as he is Indian. The girls become friends with his son and see first hand how nastily some people treat them.
During their investigations Miv and Sharon come across racism, bullying, domestic violence, alcoholism and much more. Miv is sure that if they can find out who the Ripper is then her family will not have to move house and move away from Yorkshire and her friend.
