Husband at home in resting place, running late (6)
I believe the answer is:
behind
'running late' is the definition.
(behind schedule)
'husband at home in resting place' is the wordplay.
'husband' becomes 'h'.
'at home' becomes 'in' (similar in meaning).
'in' is an insertion indicator.
'resting place' becomes 'bed' (where you can sleep or rest).
'h'+'in'='hin'
'hin' placed into 'bed' is 'BEHIND'.
(Other definitions for behind that I've seen before include "Hidden by; bottom" , "backing" , "Hidden by; late" , "Posterior, derriere" , "support" .)
