Shabby trick binding husband in the interim (9)
I believe the answer is:
meanwhile
'in the interim' is the definition.
(I've seen this before)
'shabby trick binding husband' is the wordplay.
'shabby' becomes 'mean' (both can mean unkind or unfair).
'trick' becomes 'wile' (wiles are tricks or deceptions).
'binding' means one lot of letters goes inside another.
'husband' becomes 'h' (abbreviation).
'wile' going around 'h' is 'while'.
'mean'+'while'='MEANWHILE'
(Other definitions for meanwhile that I've seen before include "simultaneously" , "On the other hand" , "For the moment" , "in intervening period" , "In the interim" .)
