The Rest is Silence - The Shakespeare Murders, #1

The director of the AWB Theatre Company, Lawrence Mickelman, has alienated everyone in sight with his tyrannical manner. When his body is found in the locked Bouwerie Lane Theatre, a sword from Hamlet in his chest, the troupe's owner asks Mark Louis, one of the actors, to dig a little deeper than she thinks the police will. The police investigation points toward Don Lovett, the play's Hamlet, but Mark's suspicions turn elsewhere.
As the police prepare to arrest Don, Mark must bring the murderer out into the open before the killer strikes again.
