(14th volume of the Wilsberg series) Only gradually does Georg Wilsberg realize that he has captured the last moment in the life of Professor Günter Kaiser on camera. A bullet abruptly ends the linguist's attempt to make an inappropriate advance towards a student, and what started as a simple surveillance assignment from the professor's wife has turned into a murder case. Since his client, now a widow, is suspected by the police and he finds her quite sympathetic, Wilsberg begins to investigate and uncovers a web of intrigue and questionable relationships within the halls of the venerable Westfälische Wilhelms-Universität. There were many reasons for wanting to send the despised linguist to the afterlife: from the professor's estranged son to the exploited assistant and her jealous husband, and even to the deeply involved.
