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' is hidden within 'manila'.
'found' is the link.
(Other definitions for nil that I've seen before include "Nix, nada, nothing" , "You get nothing" , "Love" , "Latin zero" , "There's nothing left" .)
