When she learns of a new clue to the legend surrounding Laughing Pipes Mill, Evelyn is more eager than ever to discover what is hidden there. However, with Oliver and his sister at the cottage, more mysteries arise, and Evelyn and her new friends are left with a still bigger puzzle when they discover what is within the ancient mill. For Evelyn's family to return home and peace to be restored between the sister kingdoms, the mystery solvers of Laughing Pipes Mill must all work as a team, but that may be more challenging than it appears.
We spend more time with our established cast from the first book as they work toward solving a localised puzzle only to find answers which broaden their quandary. Ulterior guises are unveiled, tensions are created and stakes are raised as the disharmony of two neighboring kingdoms brings into focus the peril of our main character Evelyn's family and their imperiled ability to return home.
