Was he after some of that bundle? (5)
I believe the answer is:
sheaf
'that bundle?' is the definition.
('sheaf' can be a synonym of 'bundle')
'was he after some' is the wordplay.
'some' indicates a hidden word.
'SHEAF' can be found hidden inside 'was he after'.
'of' acts as a link.
(Other definitions for sheaf that I've seen before include "set of papers" , "Collection of papers" , "Bundle, of grain stalks say" , "Bundle as of arrows or corn stalks" , "Bundle of several things tied together" .)
