Rosina follows the trail of crime from Hamburg to London in April of the year 1770. In Hamburg, a respectable printer is murdered, and a girl along with a valuable coin collection disappears. A few weeks later, the body of a young woman is found in London. Who hated the printer so much? Why did the girl have to die? This time, the Hamburg comedienne Rosina, along with Weddemeister Wagner and Madame Augusta, embarks on a search for a murderer and his motive in the bustling, cosmopolitan city on the Thames. An exciting quest unfolds as they navigate between the theater, coffeehouse, printing shop, seedy gin cellar, and elegant salon, uncovering the connection between the two dead bodies by the Elbe and Thames. This is Rosina's sixth case.
