Pried regularly into US deeds (5)
I believe the answer is:
nosed
'pried' is the definition.
('nose' can be a synonym of 'pry')
'regularly into us deeds' is the wordplay.
'regularly' indicates alternate letters (regularly take one letter, leave next etc.).
'into'+'us'+'deeds'='intousdeeds'
The alternate letters of 'intousdeeds' are 'NOSED'.
(Other definitions for nosed that I've seen before include "smelt" , "Beginner" , "Moved slowly and cautiously forward" , "Scented" , "See 1 Across" .)
