NEW THRILLER

Sweetpea

Thursday, 9pm, Sky Atlantic & Sky Showcase (box set, Sky Box Sets & NOW)

Ella Purnell takes on a twisted role as a wallflower who develops a liberating taste for murder in Sweetpea, a darkly comic six-part thriller from Sky Atlantic, based on the series of books by C.J. Skuse.

The Yellowjackets star plays Rhiannon Lewis, an unassuming receptionist at the Carnsham Gazette newspaper who's overlooked for promotion and struggles to make an impression with the guy she likes.

So when her dog is run over and her father - the only person in her life she can really rely upon - passes away, Rhiannon finally snaps and sets off on a murderous rampage to take vengeance on everyone who has wronged her.
