Trust you are doing well..
Am following the duke's murder quest initiated through conversation with Commander Ralph.

Am supposed to meet an assassin named Cybu at an abandoned house in Verdistis and secure a confession out of him for Ralph to attempt an arrest..
... this house is locked .. and i am not too keen on investing skillpoints in lockpick..
is there a key lying around.. or any item/book with lockpick skills that i can purchase to advance this questline?
