gorgonzola

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

'italian town' is the definition.
(I've seen this before)

'terrible female novelist' is the wordplay.
'terrible female' becomes 'gorgon' (I can't explain this - if you can you should give a lot more credence to this answer).
'novelist' becomes 'zola' (Zola is an example).
'gorgon'+'zola'='GORGONZOLA'

'in' acts as a link.

Can you help me to learn more?

(Other definitions for gorgonzola that I've seen before include "Italian town" , "Blue-veined cheese" , "Italian blue cheese" , "Big cheese" .)

I've seen this clue in The Times and The Sunday Times.
