One mustn't be quick to take umbrage so? (4,2,4,5)
I believe the answer is:
turn in ones grave
I'm afraid I can't even guess how this answer relates to the clue.
Can you help me to learn more?
(Another definition for turn in ones grave that I've seen is " react, although late".)
I've seen this clue in The Times.
Want a hint initially instead of a full solution?
