The novelist David Mitchell has started to publish an original 6000-word short story via Twitter (@david - mitchell).
Each day, a morning and afternoon dose will add about 20 new segments to The Right Sort, a tale set in 1978 and related to his new novel The Bone Clocks.
Prescription drugs, and their effect on the mind, will have a part to play. Mitchell, best known for expansive, fantastical and cleverly sub-divided novels such as Ghostwritten and Cloud Atlas, is using his tweets to break down fiction into its atomic units.
After a single day of posts, the mini-episodes of The Right Sort offer teasing glimpses of cross-class and cross-generational intrigue, as young Nathan and his divorced mum take the bus to visit Lady Briggs at her down-at-heel townhouse.
So far, it feels closer to the teenaged perplexity and social comedy of Mitchell's Black Swan Green than to his more outlandish inventions.
