Heroin, gold and pounds in takings from robbery (4)
I believe the answer is:
haul
'takings from robbery' is the definition.
(an amount of goods obtained illegally)
'heroin gold and pounds' is the wordplay.
'heroin' becomes 'h' (synonyms).
'gold' becomes 'au' (Au is the chemical symbol for gold).
'and' means one lot of letters go next to another.
'pounds' becomes 'l' (L can represent the monetary pound).
'h'+'au'+'l'='HAUL'
'in' is the link.
(Other definitions for haul that I've seen before include "Draw slowly or heavily" , "Tug; swag" , "Drag along behind" , "Drag; booty" , "Catch of fish; drag" .)
