Join the kids as they follow the case across wild West London, culminating at the colourful Notting Hill carnival - the biggest party of the year! How will they piece together the evidence to solve the mystery at the heart of London's most famous sights?
Praise for Sharna Jackson: 'I utterly loved The Good Turn; it's bone-deep brilliant; a joy to the very end. It's so warm and so funny, and so ferociously on the side of justice and of hope. I adored it.' - Katherine Rundell
