I did something similar but i was stealing things and one of the things you can do if you have enough strength you can just move the objects out the house or in some place where people can see and as i was doing it i by accident picked it up and gotten harbour against me.
The best thing was i had only 2 party members but they had lone wolf trait which is op and imanaged to kill everyone but it was long and hard fight and btw i was level 2 had cleric and ranger.
