The fourth in this series of middle-grade mysteries set in the 30s takes readers back to Deepdean School, with a new cast of characters and a thrilling murder - committed using a hockey stick, naturally Daisy Wells and Hazel Wong have returned to Deepdean for a new school term, but nothing is the same. There's a new Head Girl, Elizabeth Hurst, and a team of Prefects - and these bullying Big Girls are certainly not good eggs. Then, after the fireworks display on Bonfire Night, Elizabeth is found - murdered.
