Offer to cover tracks reflected trouble (7)
I believe the answer is:
disturb
'trouble' is the definition.
(synonyms)
'offer to cover tracks reflected' is the wordplay.
'offer' becomes 'bid' (synonyms).
'to cover' means one lot of letters goes inside another.
'tracks' becomes 'ruts' (rut can mean a track).
'reflected' says the letters should be written backwards (letters reflected back).
'bid' placed around 'ruts' is 'brutsid'.
'brutsid' reversed gives 'DISTURB'.
(Other definitions for disturb that I've seen before include "Make anxious" , "Molest" , "Unsettle, discomfit" , "Discompose" , "Intrude on" .)
