Doctor Who (2005 - Present): The Shakespeare Code

A young woman is serenaded from her balcony by a lute-playing suitor, Wiggins. She bids him enter the house, but to his shock he finds it full of witching artefacts. The woman, Lilith, kisses Wiggins — but, on pulling away, he finds her transformed into a wrinkled hag. She introduces her two "mothers", Doomfinger and Bloodtide, who appear, cackling, and lunge at the screaming youth, apparently devouring him.

Meanwhile, the TARDIS lands in Elizabethan London. Martha questions whether it is safe to walk around in the past, citing such time travel concepts as the Grandfather paradox and a reference to the Ray Bradbury short story "A Sound of Thunder"; and also worrying about her reception as a black woman in a time when slavery still exists. The Doctor tells her not to worry. He declares that they have arrived in London in about 1599 [4] and takes her to a performance at the Globe Theatre. At the end of the play, Love's Labour's Lost, Shakespeare announces that there will soon be a sequel called Love's Labour's Won. Lilith, using a poppet, influences Shakespeare to declare, rashly, that the new play will premiere the following evening. Martha asks why she has never heard of Love's Labour's Won. The Doctor knows of the lost play and, curious, decides to find out more about why it was never published — and extends Martha's "one trip".
