The low-down from one of the prisoners? (6,5)
I believe the answer is:
inside story
'prisoners?' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.
'the low-down from one of' is the wordplay.
I cannot really understand how this works, but
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is found in the answer.
'down' could be 'd' and 'd' is present in the answer.
'from' could be 'in' (I've seen this in other clues) and 'in' is found in the answer.
'one' could be 'i' (Roman numeral) and 'i' is found within the answer.
'of' could be 'o' and 'o' is present in the answer.
This explanation may well be incorrect...
'the' acts as a link.
Can you help me to learn more?
(Other definitions for inside story that I've seen before include "account of life behind bars?" , "First-hand" .)
