You found a note signed with an 'S' upon the body of a brigand while trying to recover the goods stolen from Oserley.
'This is dire news if Saruman seeks to undermine our people. You should take this note to Thane Ordlac...he will wish to know what has transpired. He is young, but he is wise.'
Thane Ordlac is in the Mead Hall of Oserley.
