Questionable, suspect (7)

I believe the answer is:

dubious

I believe this clue is a double definition.

'questionable' is the first definition.
(similar in meaning)

'suspect' is the second definition.
(I've seen this before)

(Other definitions for dubious that I've seen before include "unreliable" , "Arousing suspicion" , "Morally suspect" , "Uncertain - suspect" , "Unsure, unconvinced" .)

I've seen this clue in The Times.
