Roman Garstang is obsessed with food - particularly Squidgy Splodge raspberry-jam doughnuts - but he is about to learn that things are not always as sugar-coated as they might seem. Because of his Monday-morning jam doughnut, Roman’s week takes a very sticky turn…

By Friday Roman has been banned from eating for 24hrs, narrowly avoided a faceful of warm toddler-wee, accidentally shoplifted, been given a lift in a getaway van, styled his teacher’s guinea pig with a blue mohawk, started an OAP riot… and still barely managed to scoff a crumb - or lick - of a single doughnut.

Who knew jam could be so deadly?
