Trustworthy hand (8)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
straight
This clue is a double definition.
'trustworthy' is the first definition.
(thesaurus)
'hand' is the second definition.
(thesaurus)
(Other definitions for straight that I've seen before include "Liking the opposite sex" , "Without curve or bend" , "Without deviations or curves" , "proper place" , "Honest, not crooked" .)
