Left good books in pile for auction (3)
I believe the answer is:
lot
'pile for auction' is the definition.
'left good books' is the wordplay.
'left' becomes 'l' (common abbreviation).
'good books' becomes 'ot' (Old Testament).
'l'+'ot'='LOT'
'in' acts as a link.
(Other definitions for lot that I've seen before include "Nephew of Abraham - batch" , "A person's luck" , "Kismet" , "Survivor in Sodom" , "Where filming may take place" .)
