Discovering an unspecified number escaped from imprisonment, put a hundred back in (9)
I believe the answer is:
detection
'back in' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
I can't explain the remainder of the clue.
Can you help me to learn more?
(Another definition for detection that I've seen is " Discovery".)
I've seen this clue in the Sydney Morning Herald.
Want a hint initially instead of a full solution?
