Theatre of War

Hamlet, thou hast thy father much offended.

Ace stared at the Doctor. He nodded. 'Yes, Ace. We’re in Elsinore. And I don’t like it either.'

Five years ago, an archaeological expedition came to Menaxus to explore the ruins of an ancient theater. All but one of the visitors died horribly, and the planet was abandoned, bathed in lethal radiation. 

Now the only survivor has returned, determined to uncover the theater's secrets whatever the cost. Among her archaeological team is a certain Professor Bernice Summerfield. 

Soon the deaths begin again, while the front line of an interstellar war moves ever closer. Desperate for help, Bernice tries to summon her companions. But when the TARDIS lands on the planet, the Doctor finds himself participating in a frighteningly real performance of Shakespeare's greatest tragedy. And he begins to realize that the truth about Menaxus may be far stranger than anyone imagines.
