Unscrupulous dealer of dope meeting two Roman couples? (4)
I believe the answer is:
spiv
'unscrupulous dealer' is the definition.
(I've seen this before)
'dope meeting two roman couples?' is the wordplay.
'dope' becomes 'sp' (betting slang for SP, starting price).
'meeting' is a charade indicator (letters next to each other).
'two roman couples?' becomes 'iv' (I can't justify this - if you can you should believe this answer much more).
'sp'+'iv'='SPIV'
'of' acts as a link.
Can you help me to learn more?
(Other definitions for spiv that I've seen before include "Wide boy" , "Flashy rogue" , "Flashy dresser who makes a living by dubious means" , "wheeler-dealer" , "Old black marketeer" .)
