The stories in the books? (8)
I believe the answer is:
accounts
'the stories' is the definition.
('account' can be a synonym of 'story')
'books?' is the wordplay.
I cannot really understand how this works, but
'books?' could be 'nt' (abbreviation for New Testament) and 'nt' is present in the answer.
This explanation may well be incorrect...
'in the' acts as a link.
Can you help me to learn more?
(Other definitions for accounts that I've seen before include "Rates" , "Gives financial reckoning, or explains cause" , "Narrative descriptions of events" , "bills" , "Record of financial transactions" .)
