Double agent picked up booze (7)
I believe the answer is:
replica
'double' is the definition.
(thesaurus)
'agent picked up booze' is the wordplay.
I cannot quite understand how this works, but
'agent' could be 'rep' (short for representative) and 'rep' is found 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 replica that I've seen before include "Exact copy or model" , "Parcel I found with exact copy" , "Parcel I arranged as exact copy" , "Copy original" , "Reproduction, fascsimile" .)
