Novel fish store (5,5)
I believe the answer is:
bleak house
'novel' is the definition.
(Charles Dickens novel)
'fish store' is the wordplay.
'fish' becomes 'bleak' (I've seen this before).
'store' becomes 'house' (to house is to store something).
'bleak'+'house'='BLEAK HOUSE'
(Other definitions for bleak house that I've seen before include "7 27's [CHARLES DICKENS] book" , "* [DICKENS WORK]" , "Novel by Dickens" , "Novel satirising the old court of Chancery" , "Dickens' desolate domicile" .)
