Bookie's client recovered (6)
I believe the answer is:
better
This clue might be a double definition.
'bookie's client' is the first definition.
The definition and answer can be both people as well as being singular nouns.
Maybe there's a link between them I don't understand?
'recovered' is the second definition.
(I've seen this before)
Can you help me to learn more?
(Other definitions for better that I've seen before include "More able" , "Top" , "cap" , "Superior; gambler" , "he will take risks" .)
