Then we have to talk with him: not in his house, because there´s a real one there and our disguise wont last is we meet him."
"So we have to get our hands on him when he´s out of the house and 'convince' him to say us where the evidence is. I´m sure many of you have the tongue silvered enough for that, and some of my magic could help us. Then we enter the house, get the evidence and get out as quick as we can: again, I have magic for that. The later while we hold the noble at a secure place."
