Starts fixing a stone in a deceptive action (4,3)
I believe the answer is:
fast one
'a deceptive action' is the definition.
'fast one' can be an answer for 'action' (fast one is a kind of action). I am not sure about the 'a deceptive' bit.
'starts fixing a stone' is the wordplay.
'starts' indicates taking the first letters.
The first letter of 'fixing' is 'f'.
'f'+'a'+'stone'='FAST ONE'
'in' is the link.
Can you help me to learn more?
(Other definitions for fast one that I've seen before include "might be pulled by 20 [HUSTLER] ?" , "Such as Bolt" , "may have been pulled in cheating allegation?" , "Runner" .)
