Shows embarrassment in places socialists frequent? (7)
I believe the answer is:
reddens
'shows embarrassment' is the definition.
'places socialists frequent?' is the wordplay.
I cannot really see how this works, but
'places' could be 'dens' (den is a kind of place) and 'dens' is located in the answer.
The remaining letters 'red' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'in' acts as a link.
Can you help me to learn more?
(Another definition for reddens that I've seen is " Blushes".)
