“Let’s do that,” Camistella agreed. “Try checking Shingen and, in particular, the Guild of Wonders. I already advised you to do this. The Black Knight was definitely there in person. That’s where I committed the murder, and that’s where the archmage died. If Shingen turns out to be clean, then Stalemida will remain the only lead. As for your house… I don’t have any ideas here. We could try to check every corner for cursed energy, but that doesn’t sound very promising.
It’s unlikely that this house had a secret basement where the Black Knight spent his time.
