A Catholic peer reveals his story (7)

I believe the answer is:
account
'his story' is the definition.
'account' can be an answer for 'story' (synonyms). I'm not sure about the 'his' bit.
'a catholic peer' is the wordplay.
'catholic' becomes 'C' (abbreviation as in RC for Roman Catholic).
'peer' becomes 'count'.
'a'+'c'+'count'='ACCOUNT'
'reveals' is the link.
Can you help me to learn more?
(Other definitions for account that I've seen before include "News report" , "Statement of transactions and costs" , "Bank record" , "Report of an event" , "Charge" .)
