Script of bodice ripper originally found in abandoned toilet (8)
I believe the answer is:
libretto
'script' is the definition.
(I know that libretto is a type of script)
'bodice ripper originally found in abandoned toilet' is the wordplay.
'originally' indicates taking the first letters.
'found in' is an insertion indicator.
'abandoned' indicates anagramming the letters (the original order is abandoned).
The initial letters of 'bodice ripper' is 'br'.
'toilet' is an anagram of 'lietto'.
'br' going within 'lietto' is 'LIBRETTO'.
'of' acts as a link.
(Other definitions for libretto that I've seen before include "Operatic text" , "11 down book" , "Book of words of an opera" , "Operatic book" , "Text set to music in opera" .)
