Birds of a Feather - Season 4 Episode 11 -

Dorien has completed her bonkbuster novel and its publication is forthcoming but, concerned that Marcus doesn't identify her with some of the heroine's racy escapades, she gives Sharon's name as the authoress. Sharon puts up a convincing charade when he publisher calls but when a re-write is called for and Dorien is away on holiday, five people have to collaborate on the chapter.
