Seafood racket attracting detective (6)
I believe the answer is:
scampi
'seafood' is the definition.
(I've seen this before)
'racket attracting detective' is the wordplay.
'racket' becomes 'scam' (I've seen this before).
'attracting' says to put letters next to each other.
'detective' becomes 'pi' (I've seen this in other clues).
'scam'+'pi'='SCAMPI'
(Other definitions for scampi that I've seen before include "Large prawns as food" , "Norway lobsters -- Dublin Bay prawns" , "Large sauteed prawns" , "Edible crustaceans" , "Cooked Norway lobsters" .)
