Discover I have new work of fiction (9,5)

I believe the answer is:

detective novel

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

'work of fiction' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.

'discover i have new' is the wordplay.
'discover' becomes 'detect' (synonyms).
'i have' becomes 'I've' (contraction of 'I have').
'new' becomes 'novel' (similar in meaning).
'detect'+'ive'+'novel'='DETECTIVE NOVEL'

Can you help me to learn more?

(Another definition for detective novel that I've seen is " book?".)

I've seen this clue in The Daily Express.
