Bloody fantastic job (without catch)! How did you get it? (3,3,7)
I believe the answer is:
old boy network
'did you get it?' is the definition.
I can't tell whether this definition defines the answer.
'bloody fantastic job without catch' is the wordplay.
I cannot quite see how this works, but
an anagram of 'bloody' is 'oldboy' which is located in the answer.
'job' could be 'work' (synonyms) and 'work' is found within the answer.
'catch' could be 'net' (net can mean to catch) and 'net' is present in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'how' acts as a link.
(Other definitions for old boy network that I've seen before include "Group that does each other favours -- not rowdy bloke (anag)" , "Social support system" , "Mutual aid system of former colleagues" , "Form of nepotism" , "System of mutual assistance" .)
