The beggar's death raises more questions for Norah. When the body was found, she suddenly received a message from an unknown number warning her about Arthur Grimm. "Arthur Grimm is dangerous!" is the ominous message. But the mysterious sender does not identify himself. Together with her neighbor Theresa, Norah ponders who the message could be from and who Arthur Grimm is. But both of them can't figure it out. As expected, Norah's work on the Balder portrait is complicated. At a vernissage, Norah even clashed loudly with the artist. After all, Norah gets along better with her colleague Emil after initial difficulties. If Emil had his way, the collegial relationship could develop into something more.
