Lad welcomes organisation by team leader following game - if there's a catch, he'll make sure it's a profitable one (6,6)
I believe the answer is:
bounty hunter
'lad welcomes organisation by team leader following game if there's a catch he'll make sure it's a profitable one' is the definition.
The definition suggests a singular noun which matches the answer.
'catch he'll make sure it's a profitable one' is the wordplay.
I cannot quite see how this works, but
'catch' could be 'hunt' (hunting is a kind of catching) and 'hunt' is present in the answer.
'one' could be 'un' (I've seen this in other clues) and 'un' is found in the answer.
'it' could be 't' (abbreviation. e.g. in 'tis) and 't' is located in the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for bounty hunter that I've seen before include "trailer for cash" , "Mercenary lawman" , "One might get a reward after shooting" , "One pursuing fugitives for a reward" , "Chaser of criminals for reward" .)
