Sexy books found in Morecambe? (6)
I believe the answer is:
erotic
'sexy' is the definition.
(similar in meaning)
'books found in morecambe?' is the wordplay.
'books' becomes 'OT' (Old Testament).
'found in' means one lot of letters goes inside another.
'morecambe?' becomes 'eric' (comedian Eric Morecambe).
'ot' going inside 'eric' is 'EROTIC'.
(Other definitions for erotic that I've seen before include "Sexy" , "Intended to arouse" , "Titillating" , "Conducive to arousing sexual desire" , "Relating to sexual pleasure" .)
