Adam passes Bantorget on his way to and from the police station. Defence lawyer Michael Blomberg's office is described as being around the corner from Bangatan on Klostergatan, three floors up and overlooking this square.
The novel gives no exact building. The safest way to picture the scene is that the office would have occupied one of the buildings facing Bantorget—not that any particular window belongs to the fictional lawyer.
This is a useful place to think about professional authority. Adam believes his position as a pastor makes him trustworthy, Ulrika understands the law, and Blomberg understands how stories are presented in court. The family is surrounded by institutions that claim to establish truth, yet private truth remains much harder to determine.
