Falsely accused prisoner — uncontrollable fury dies when one is released (7)

I haven't cracked this one yet — but the brilliant team at Fifteensquared have:

An anagram (‘uncontrollable’) of ‘fury d[i]es’ minus the I (‘when one is released’). L’Affaire Dreyfus was a French miscarriage of justice as a result of which Alfred Dreyfus served nearly five years on Devil’s Island, being eventually pardoned and then exonerated. The ‘fury’ was stoked by Émile Zola’s letter J’accuse…! , so the clue has an extended definition.
