She wants some more money (4)

I believe the answer is:

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

'she' is the definition.

'some more money' is the wordplay.
'some more' becomes 'mol' (I can't justify this - if you can you should give a lot more credence to this answer).
'money' becomes 'l' (L can mean 'pounds').
'mol'+'l'='MOLL'

'wants' acts as a link.

Can you help me to learn more?

(Other definitions for moll that I've seen before include "Gangster's female companion", "Gangster's girlfriend", "Book by Defoe", "Hood's girl", "Gangster's girl".)

I've seen this clue in Evening Standard.
