Divorcee, one in bed, offers adventure (7)
I believe the answer is:
exploit
'adventure' is the definition.
(I've seen this in another clue)
'divorcee one in bed' is the wordplay.
'divorcee' becomes 'ex' (I've seen this in other clues).
'one' becomes 'I' (Roman numeral).
'in' means one lot of letters goes inside another.
'bed' becomes 'plot' (I've seen this before).
'i' placed within 'plot' is 'ploit'.
'ex'+'ploit'='EXPLOIT'
'offers' acts as a link.
(Other definitions for exploit that I've seen before include "Benefit from" , "Daring feat; use unfairly" , "Make use of - great deed" , "Heroic achievement" , "Make use of - achievement" .)
