I don't know what scene you saw up to...but Munster went to the university to talk to the professor who wrote the thesis (that the "snob" told them about earlier) about the novels in question. When he got to her office, Maarten the murder was there. Turns out the professor was his wife, the woman he strangled in the first scene. He tells Munster he'll give him all his wifes notes on Fist, which are in the basement. While Maarten is on a ladder "retrieving" the notes, Munster notices he is wearing the thatched shoes he saw through the post slot. They fight, Munster's arm is slashed and he fatally stabs Maartan. Maarten stumbles out of the building and bystanders come to his aid. The last scene is of him returning the office with renewed confidence. Eva tells him Jaan is gone and he apologizes for interfering with their relationship. She then teases him and asks if he wants to know why she didn't tell Jaan that Munster told her Jaan was seeing others. He said no, then chased her out of the office to find out why...:)
