"Brisk pacing, sophisticated writing, and deftly woven parallel plots build to a satisfying conclusion. The banter and bickering between both sets of twins are especially authentic, and fans of historical fiction will enjoy the many details about life in eighteenth-century Scotland."

—Magan Szwarek, Booklist Online Exclusive, February 6, 2015

One day, Will and Lucy's dad just...vanishes. They have no idea why he's disappeared until a creepy stranger reveals their dad was keeping a BIG secret. Then there's the second clue: an old diary they find hidden in the walls of their Royal Mile house, with a sinister black dagger on it.

If they want to find their dad and bring him home, Will and Lucy must solve a mystery that's more than two hundred years old. But can they find the answers in time to rescue him?

Award-winning author Joan Lingard weaves a fast-paced mystery set in and around Edinburgh's Royal Mile. The story alternates between Will and Lucy, searching for their dad in the present day, and their ancestors William and Louisa, struggling to save their own father while following the sign of the black dagger and uncovering a plot to kill a French aristocrat.
