Asia fast in dismantling scam? That’s healthy (2,3,2,1,6)
I believe the answer is:
as fit as a fiddle
'asia fast' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.
'dismantling scam? that's healthy' is the wordplay.
'dismantling scam?' becomes 'as' (I can't explain this - if you can you should believe this answer much more).
'that's healthy' becomes 'fitasafiddle' (I've seen this in another clue).
'as'+'fitasafiddle'='AS FIT AS A FIDDLE'
'in' is the link.
Can you help me to learn more?
(Another definition for as fit as a fiddle that I've seen is " in form!".)
