Falsely accused prisoner — uncontrollable fury dies when one is released (7)
I believe the answer is:
dreyfus
'falsely accused prisoner uncontrollable' is the definition.
I can't judge whether this defines the answer.
'fury dies when one is released' is the wordplay.
I cannot quite see how this works, but
'when' could be 'e' (I've seen this in other clues) and 'e' is present in the answer.
an anagram of 'fury' is 'ryfu' which is within the remaining letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for dreyfus that I've seen before include "Frenchman involved in affair" , "French army officer" , "The - Affair in France concerned a wrongly imprisoned officer" , "- Affair, in which Zola was involved" , "French captain, wrongly convicted 1894" .)
