One horrible fella keeps maiden in disrepute (3,4)
I believe the answer is:
ill fame
'disrepute' is the definition.
(I've seen this before)
'one horrible fella keeps maiden' is the wordplay.
'one' becomes 'I' (Roman numeral).
'horrible' indicates anagramming the letters.
'keeps' is an insertion indicator.
'maiden' becomes 'm' (cricket abbreviation).
'fella' anagrammed gives 'llfae'.
'llfae' placed around 'm' is 'llfame'.
'i'+'llfame'='ILL-FAME'
'in' acts as a link.
(Other definitions for ill fame that I've seen before include "Disrepute" , "bad reputation" , "notoriety" , "bad report" , "A house of . . . . . . . is a brothel" .)
