Distrust (6)
'distrust' is the definition.
(I know that distrust can be written as suspect)
This is the entire clue.
(Other definitions for suspect that I've seen before include "Funny" , "Possible criminal - doubtful" , "Fancy" , "Questionable" , "Person being accused" .)
(Other definitions for doubts that I've seen before include "Has reservations, is uncertain" , "Misgivings" , "Suspicions" , "Thinks something unlikely" , "Uncertainties" .)
