Piggy Monk Square is a dark and humorous novel. Rebecca's parents are splitting up. Her best friend, Debbie, has a father who is constantly in and out of prison.
Their world is dark, confusing and frequently brutal and the two girls tend to mix reality with fantasy - especially when it comes to coping with what will soon become their terrible secret.
One day, Rebecca and Debbie are playing in the cellar of a derelict house when a policeman warns them to keep away from there. But this is their favourite place to play.
When they can't keep away and are again caught by the very angry policeman, They 'leg it.'
He chases them but he falls down a ladder and goes 'asleep.' The girls have been taught not to trust the police and are so terrified of getting into trouble that they don't tell anyone.
The injured policeman is unable to escape the cellar and becomes dependent on the two girls.
But, their efforts to help him have disastrous consequences for them all.
