Book with info but no introduction (4)
I believe the answer is:
acts
'book' is the definition.
(book of the Bible)
'info but no introduction' is the wordplay.
'info' becomes 'facts'.
'but no introduction' means to remove the first letter.
'facts' with its first letter taken off is 'ACTS'.
'with' is the link.
(Other definitions for acts that I've seen before include "New Testament book immediately following the Gospels" , "Performs on stage" , "Pieces of legislation" , "individual performers in a show" , "appears (eight in a series may be found)" .)
