Kate Stanley's fame as a director with an expertise in "occult Shakespeare" catapults her - and Ben Pearl, her partner in crime solving - into a new production of Macbeth, showcasing a fabled collection of objects relating both to the play and the historical Scottish king for whom it is named. The Bard's witch-haunted play is famously cursed, and as rehearsals begin at the foot of Scotland's Dunsinnan Hill, it doesn't take long fur the curse to stir. A tarot card leads Kate to Birnam Wood, where she finds a local woman dead in circumstances that suggest not just ritual murder, but ancient pagan sacrifice.
