What mystery is hidden in the manuscripts of Shakespeare? Kate Stanley, a young playwright, received from her friend and mentor Rosalind a strange object just before she dies murdered. The murderer wanted to make it an implicit message: the exact recreation of the death of Hamlet's father through the crime committed. Kate knows that the answers to the enigma that Rosalind has left are hidden somewhere between the original manuscripts of the writer. Her search with the murderer always following her, takes her from the dark libraries of London to the deserts of Arizona. The reward: the greatest secret of literary history. The stakes: life itself.
