While exploring the attic in her cottage, Lori Shepherd discovers a gold bracelet that had once belonged to Aunt Dimity. It is a poignant moment for Aunt Dimity, awakening memories of London after the War, and she asks Lori to do what she could not: return the bracelet to her unsuccessful suitor. Lori is off on an adventure through London—and through history—and in this 21st adventure (after Aunt Dimity and the Summer King), she uncovers a link between her aunt's long-lost beau and a buried treasure that newcomers have found in the village.
