Nothing found in Manila (3)
I believe the answer is:
nil
'nothing' is the definition.
(eg nil is zero in football)
'in manila' is the wordplay.
'in' indicates the answer is hidden within the clue.
'NIL' can be found hidden inside 'manila'.
'found' acts as a link.
(Other definitions for nil that I've seen before include "Nix, nada, nothing" , "You get nothing" , "Love" , "Latin zero" , "There's nothing left" .)
