Dodgy Tory -- a cheap supplier of drugs (10)
I believe the answer is:
apothecary
'supplier of drugs' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'dodgy tory a cheap' is the wordplay.
'dodgy' indicates an anagram (a dodgy or wrong order of the letters).
'tory'+'a'+'cheap'='toryacheap'
'toryacheap' with letters rearranged gives 'APOTHECARY'.
Can you help me to learn more?
(Other definitions for apothecary that I've seen before include "Drug supplier" , "Old-style chemist" , "Drug dispenser" , "dealer, old-style" , "Old-style pharmacist" .)
