She has, after all, been asked to accept numerous bad things over the last few days. It would not be entirely out of place for her to suffer some kind of adverse emotional reaction. Or perhaps this is just fury: she lost her suspect and one of her key informants, and that does not often happen to her. Lönnrot is playing with her, leading her about by the nose, and she has so much information and nowhere to put it, and Lönnrot is not even the problem, or not only and entirely. She feels hollowed out, as if she’s acting herself rather than actually being there.
