No reaction from the gagged and blindfolded person? (3,1,4)
I believe the answer is:
not a peep
'no reaction' is the definition.
I don't know anything about this answer so I can't tell whether this works.
'from the gagged and blindfolded person?' is the wordplay.
I cannot really see how this works, but
'from' could be 'o' (I've seen this in other clues) and 'o' is present in the answer.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is found in the answer.
'and' could be 'n' (common abbreviation for 'and') and 'n' is found in the answer.
'person?' could be 'ape' (ape is a kind of person) and 'ape' is found within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for not a peep that I've seen before include "No noise" , "Total silence" .)
