I have been a big fan of Michael Dibdin for most of his books, enjoying the development of the fascinating character of Aurelio Zen, the tight plots, and the most insightful Italian context.
The last 2 or 3 books, however, have made me cool off somewhat, and this last one - Back to Bologna - I found awful. The characters were mostly caricatures, with far too much extraneous guff spent on what might be thought of as their development; the hero and his partner had gone completely off the rails, and the plot was highly questionable.
And he even had one of his police inspectors called Brunetti; what's the matter with him? I can't believe that he's not aware of Donna Leon's splendid hero.
Sorry, Michael Dibdin, the Zen series is all washed up. Try something else or leave us alone.
