From the back cover:

Beautiful and serene Venice is a city almost devoid of crime. But that is little comfort to Maestro Helmut Wellauer, a world-renowned conductor whose intermission refreshment comes one night with a little something extra in it - cyanide. For Guido Brunetti, vice-commissario of police and detective genius, finding a suspect isn't a problem; narrowing the large and unconventional group of enemies down to one is. As the suave and pithy Brunetti pieces together clues, a shocking picture of depravity and revenge emerges, leaving him torn between what is and what should be right - and questioning what the law can do, and what needs to be done.

The first of the Guido Brunetti mysteries, which have grown on me quite a bit. The backcover text of this American edition comes off a bit funny to me. I have read this mystery before in Finnish, and I quite liked the opera setting (which Leon has returned to a couple of times, including a few of the characters).

This paperback will be released in a suitable setting eventually.

Left in the book-exchange shelf of the main library. Happy trails and happy reading!
