A bowler's trick? (3)
I believe the answer is:
hat
This might be a double definition.
'a bowler's' is the first definition.
(I've seen this in other clues)
'trick?' is the second definition.
The answer and definition can be both acts as well as being singular nouns.
Perhaps you can see a link between them that I can't see?
Can you help me to learn more?
(Other definitions for hat that I've seen before include "Eg, derby" , "One to cover head" , "Bowler maybe" , "Head-covering" , "Cap" .)
