On the eve of a production of Hamlet at Shakespeare's Globe, Shakespeare scholar and theater director Kate Stanley’s eccentric mentor, Harvard Professor Roz Howard, gives her a mysterious box, claiming to have made a groundbreaking discovery.

But before she can reveal it to Kate, the Globe burns to the ground and Roz is found dead, murdered precisely in the manner of Hamlet’s father.

Inside the box Kate finds the first piece in a Shakespearean puzzle, setting her on a deadly, high-stakes treasure hunt.
