Apart, in pieces (7)
I believe the answer is:
asunder
I believe this clue is a double definition.
'apart' is the first definition.
(I know that apart can be written as asunder)
'in pieces' is the second definition.
(asunder means torn apart)
(Other definitions for asunder that I've seen before include "(Break) apart" , "(Torn) apart" , "being in two" , "Sad rune (anag.)" , "bits?" .)
