Mysterious clues about protagonist with roving eye (9)

I believe the answer is:

lecherous

'with roving eye' is the definition.
(as in a lecher who stares at people sexually)

'mysterious clues about protagonist' is the wordplay.
'mysterious' indicates an anagram.
'about' means one lot of letters goes inside another.
'protagonist' becomes 'hero' (I've seen this before).
'clues' is an anagram of 'lecus'.
'lecus' placed around 'hero' is 'LECHEROUS'.

(Another definition for lecherous that I've seen is " Lustful".)
