The story itself was great. Certainly better than the previous volume, "Herz aus Stahl". A dead body is found in the opera of Nürnberg. Paul Flemming is employed as the dead man's successor: photographer for the opera. As such he comes to know the opera singers and other people working at the opera. Soon he and his friend, the public prosecutor Katinka Blohm, have more than enough suspects. And then another man dies with still more suspects than what would do good.
As always the setting gives the right kind of atmosphere. The ending, although I again suspected some of it, was still suspenseful. However I really disliked the last chapter, which seemed just too forced and depicted a fact of law simply false. I wouldn't mind this if a person who hasn't studied law said that, but the character giving that false accusation is the public prosecutor herself, who should know better. ( )
