A time-twisting historical mystery, by an award-winning author
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.
Will and Lucy must solve a mystery that's over two hundred years old if
they want to find their dad and bring him home. 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.
