With hindsight, murkier culture helped them hide money (5)
I believe the answer is:
lucre
'money' is the definition.
(I know that lucre is a type of money)
'with hindsight murkier culture helped them hide' is the wordplay.
'LUCRE' is hidden backwards within the letters.
But, I am unsure how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for lucre that I've seen before include "Bread, dough, lolly" , "(Filthy) profit" , "tin" , "Money or wealth" , "Money (especially when gained dishonourably)" .)
