The Merry Christmas Murders

Every year, six local schools compete to win the Christmas Cup. Last year, the rival school to Brooke Parkin's school won for the most crackers pulled in a minute! This year, the cup will be judged and awarded to the school with the perfect mince pie. But when a series of murders seemed to be linked to the very mince pies (each with a clue from a letter from the alphabet imprinted in the pastry) the five neuro-divergent children must turn detective and combine their skill sets to find the killer. Can they prevent another death and save their out-of-school club from being shut down forever?
