"Beneath the floorboards of G. K. Chesterton's home, a thrilling pursuit is about to unfold. . . Sister Seraphina was pleased that everything was ready for the school fair. But when the prize cheese goes missing, the Sisters of Our Lady Star of the Sea and their brave students will need all their detective wits to solve the mystery.
