He meets me in SCR for Mastermind (7)
I believe the answer is:
schemer
'mastermind' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'he meets me in scr' is the wordplay.
'meets' says to put letters next to each other.
'in' means one lot of letters goes inside another.
'he'+'me'='heme'
'heme' going within 'scr' is 'SCHEMER'.
'for' is the link.
Can you help me to learn more?
(Other definitions for schemer that I've seen before include "One making devious plans" , "He plots and plans" , "Secret plotter" , "Machiavellian type" , "Plotter, conspirator" .)
