fiction

I'm a little stuck... Click here to teach me more about this clue!

'the writing' is the definition.
(fiction is a kind of writing)

I don't understand the remainder of the clue.

(Other definitions for fiction that I've seen before include "Something invented" , "Invented story" , "See 9" , "Literary form" , "Fabricated story" .)

I've seen this clue in the Evening Standard.
