Summer in Hamburg – and one song is in everyone's ear: ›Savoy Blues‹. Louis Armstrong's 1930s swing song is the year's number one hit in a cover version from DJ Jack. It can be heard in all of the cafés and from every car. It is even swirling in the ears of the recently graduated head inspector, Sebastian Fink, as he sets out to solve his own first case. The murder, which he is dealing with, does not appear to be too spectacular at first glance. A retired mailman has been found dead. But what comes out in the course of his investigations is a story deeply rooted in the past – just during that time which enjoys a revival through the summer hit, ›Savoy Blues‹. A detective story that comes across as deceptively simple and subtly lures us into the depths of the city on the Alster with its jazzy melancholic melody.
