Cheat everybody into, as you go from door to door (4,2)
I believe the answer is:
call on
'you go from door to door' is the definition.
I can't tell whether this defines the answer.
'cheat everybody into' is the wordplay.
'cheat' becomes 'con' (con is a kind of cheat).
'everybody' becomes 'all' (all people).
'into' means one lot of letters goes inside another.
'con' enclosing 'all' is 'CALL ON'.
'as' is the link.
Can you help me to learn more?
(Another definition for call on that I've seen is " Pay visit to, or appeal to".)
