Just finished the fourth book in the series and it was another great mystery. The Detective Society is back at Deepdean school but things are different and not in a good way. The head girl and her prefects are awful and everyone is miserable until a murder stirs things up and secrets start coming out and shifting the balance of power. Highly enjoyable as always!
