After Calder Cob tried to have you ambushed by the Blackwolds, Strider wishes to prove beyond a doubt that he is an enemy to Archet.
'I cannot decide which is more dangerous right now: Calder Cob's treachery or the ignorance of Captain Brackenbrook!
'If Calder Cob is his best soldier, I know Brackenbrook will not believe that he tried to have you ambushed by a Blackwold.
'I did some asking around while you were gone, and there is a Blackwold brigand in the stocks, across the lane from here; he is being held for highway robbery. You should question him about Calder Cob.'
Otto the Brigand is being held in the stocks in the Archet Jailyard, across the lane from Strider and Amdir.
You should question Otto directly about Calder Cob and the Blackwolds' treachery; Captain Brackenbrook is not ready to be convinced by your words alone.
The Archet jailor, a man named Ned Pruner, stands warily near Otto.
You should speak with Ned Pruner, for perhaps Otto had a loose tongue around his captor.
Captain Brackenbrook is in the town of Archet.
You should quickly tell Captain Brackenbrook about what Otto has said to you and to Ned Pruner, his jailor.
