Towards the back in a paper (3)
I believe the answer is:
aft
'towards the back' is the definition.
(aft means towards the back of a ship)
'a paper' is the wordplay.
'paper' becomes 'ft' (newspaper the FT, Financial Times).
'a'+'ft'='AFT'
'in' is the link.
(Other definitions for aft that I've seen before include "Astern" , "Towards the back on board" , "Near the stern" , "towards the end" , "At the back at sea" .)
