In Paris, the aristocrat gets reprieve (3,3)
I believe the answer is:
let off
'reprieve' is the definition.
(I've seen this before)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for let off that I've seen before include "given a reprieve" , "impose no punishment at all?" , "Release by exploding - pardon" , "Don't impose penalty or allow to dismount" , "Pardon - discharge" .)
