The Witches never failed to extract a price somehow.

When Cross stumbles drunkenly into a darkened Berlin theatre that is staging Hamlet, he does not expect to see Morgana le Fay on stage as Queen Gertrude or witness a real murder. But a deadly ghost is haunting the faerie queen’s plays and Morgana expects Cross to solve the mystery or risk his daughter, Amelia, becoming the next victim. With the fate of Amelia in the balance Cross tries to unravel a mystery that takes him to libraries outside of time, into battles alongside an undead Christopher Marlowe and to bargaining with the real Witches of Macbeth. But is the play the thing, or is there something far older haunting Shakespeare’s famous work?
