A black student is shot dead during a demonstration claiming "Beethoven Was Black" in Bonn's historic Münsterplatz with its majestic monument to the Bonn-born composer. Attending a Beethoven jubilee conference in the city is retired professor turned art crimes detective Megan Crespi with her American colleague and Beethoven expert, Will Meridian. During their symposium on the composer one of the participants is also killed. Who is the assassin or assassins and why do the murders continue? The cast of characters and suspects Megan is confronted with include Bettina Brentano, ambitious conductor of the Bonn Classical Philharmonic, Oskar van der Fresser, founder of the Beethoven und Du Museum in Vienna, Dr. Seide Sammlerin, over-protective director of the Beethoven-Haus Bonn, Tobias Neidisch, Beethovenhalle night guard with a chip on his shoulder, Dr. Li Shutong, with a singular background relating to Beethoven in China, Leopold Weissknab, white supremacist student studying at Bonn University, Louis van Hoven, a self-declared direct descendant of Ludwig van Beethoven, Clemens Karl von Masuren, beloved conductor of the Beethoven Orchester Bonn, and Takuto Nisemono, conductor and composer once considered "the Beethoven of Japan," now disgraced but defiant and scheming a come-back. Megan's pursuit of Beethoven-related criminal activity extends to a cruise ship bound for China and additional deaths. Can justice prevail?
