Sefton Scott welcomes parents, students and teachers to Kemble Martyrs Boys School fete. Bunty eyes an egg and spoon race and Mrs McCarthy agrees to compete with her. Heading towards the cake table, Father Brown meets a pupil from the Girls' School next door, May Lewis who swipes the last three macaroons. Even though he's meant to be the best, Sefton's grandson Daniel Gates gives a poor cricket demonstration, but Mrs McCarthy thrives in the egg and spoon race and takes home the rosette. Meanwhile, the deputy headmaster of the school, Philip sneaks away with Sheila, the deputy head of the girl's college next door, but to their horror, they find May on the floor, her head pooling with blood.
