The BBC is adapting a modern novel about the fallout from a chance sexual encounter in the Houses of Parliament.
A four-part adaptation of Louise Doughty’s Book Apple Tree Yard will air on BBC1, probably next year.
The novel centres on Yvonne Carmichael, an eminent geneticist in her early 50s, and begins with her giving evidence to a Parliamentary Select Committee.
On her way out of the building, the happily married Carmichael catches the eye of a man and they have sex in the crypt chapel – an event that has disastrous consequences for her.
The drama, which has not been cast yet, has been written by Amanda Coe and is described by the BBC’s outgoing head of drama commissioning Ben Stephenson as a “complicated thriller”.
Coe’s other TV credits include the BBC period drama Room at the Top and the biopic Filth: The Mary Whitehouse story.
It is expected to air next year.
