This was my first Aurelio Zen novel, and it won't be the last. I picked up on a recommendation of sorts from Masterpiece Mystery, which will be showing the (apparently only three-episode) TV adaptation of the Zen books. The novels being adapted are this one, Cabal and Ratking, so I am reading them in broadcast order instead of series order.
Even with this being the second novel in the series, I was very easily immersed in Zen's world. Dibdin's writing is well crafted and he is not afraid to use longer, more complex sentences to tell his story. Zen comes across as a very amusing character, with plenty of cunning and street smarts but also very real insecurities and flaws. His relationship with his mother provides a good source of entertainment -- she's moved into his apartment in Rome because she can't live on her own in Venice anymore, and naturally conflict will ensue, especially when his mum acts selectively deaf and stubborn.
I loved the details of life in Rome as well: shoving one's way onto the back of a crowded bus, standing in the doorway of a bar drinking a very young wine, going to coffee bars, and everyone cutting out of work on Friday at noon. I also liked the descriptions of the other cops' conversations about cars and the part about Zen's driving style, as it is very much mine as well:
"Zen's style behind the wheel was that of an elderly peasant farmer phut-phutting along at 20 kph in a worn-out Fiat truck with bald tyres and no acceleration, blithely oblivious to the hooting, light-flashing hysteria building up in his wake." (p. 152 of the edition I read)
The only thing I didn't really like in this book was the italicized interludes, which kind of made sense at first but then I got confused about them and am not sure whether my initial assessment was correct. But that was the only quibble I had. Zen is a great character, Dibdin an excellent writer and I am very much looking forward to reading the rest of the series. This one's a keeper.
