Planner: he meets me in SCR (7)
I believe the answer is:
schemer
'planner' is the definition.
(I know that schemer is a type of planner)
'he meets me in scr' is the wordplay.
'meets' says to put letters next to each other.
'in' is an insertion indicator.
'he'+'me'='heme'
'heme' going inside 'scr' is 'SCHEMER'.
(Other definitions for schemer that I've seen before include "one inventing plots" , "Plotter and planner" , "Secret plotter" , "Cunning planner" , "Machiavelli" .)
