Champion driver perhaps one in black suit (3,2,5)
I believe the answer is:
ace of clubs
This clue could be a double definition.
'champion driver' is the first definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe you can see a link between them that I can't see?
'one in black suit' is the second definition.
(I've seen this before)
'perhaps' is the link.
Can you help me to learn more?
(Other definitions for ace of clubs that I've seen before include "finest social venue" , "brilliant Batman!" , "card?" , "one in a black suit" , "Top golfer" .)
