Simenon made a lot of noise about them (3)
I believe the answer is:
men
'noise about them' is the definition.
I can't tell whether this definition defines the answer.
'simenon made a lot' is the wordplay.
'a lot' indicates the answer is hidden within the clue (a lot of the letters from the clue).
'MEN' can be found hidden inside 'simenon made'.
'of' is the link.
Can you help me to learn more?
(Other definitions for men that I've seen before include "Soldiers" , "Fellows, chaps" , "Male humans" , "Males of Armenian extraction." , "Chess pieces" .)
