Caught in temptation to make riches (5)
I believe the answer is:
lucre
'riches' is the definition.
(thesaurus)
'caught in temptation' is the wordplay.
'caught' becomes 'c' (cricket abbreviation).
'in' indicates putting letters inside.
'temptation' becomes 'lure' (lure is a kind of temptation).
'c' inserted into 'lure' is 'LUCRE'.
'to make' acts as a link.
(Other definitions for lucre that I've seen before include "Wealth - cruel (anag)" , "Criminal gains maybe" , "(Dishonourably gained) money (poetic, literary)" , "Scornful word for money that may be 1 Across" , "ill-gotten gain" .)
