Review of Carlo Lucarelli's new novel

I had one request for an English version of my review in Italian (below) which is pretty good for a blog response. So here goes:

Between 1994 and 2000, Carlo Lucarelli, the master of italian crime fiction, published 4 novels featuring Inspector Grazia Negro, a detective in Bologna. Only two of them have been translated, Almost Blue and Day After Day. All the stories deal with a brutal serial killer. Lucarelli has just published a new novel with Inspector Negro, in 2013. After these thirteen years between the last and the newest novels, Grazia and her lover Simone (who has been in all but one of the books)are trying to have a baby, and she is hot pahhy at all to be investigating a serial killer: but Bologna has one, nonetheless.

The tracks of the killer carry the inspector and her colleague in the Carabinieri to a popular song by Andrea Buffa, The Dream of Flying (also the title of the novel). The song is comic, at the beginning. A loose translation of the first verse is:
Since I was young I've dreamt of flying like a bird,
but now when I press against the air my weight isn't a good thing,
I fly like a brick, like a stone, like a wrench
It seems obvious that flying without wings is a problem.

But Buffa is really talking about two important social issues: the story of the song deals with the death, on a construction site, of a foreign worker. And Lucarelli's serial killer wants to kill all the people who are involved in the death of a construction worker, also a foreigner. It seems as if there's not just one killer, as the murderer sends messages to the police, until a psychologist consulting on the case suggests that in fact it is one person with a multiple personality.

I've heard that most psychologists today don't believe in the diagnosis of multiple personalities, but Lucarelli has created from the idea an interesting novel from his diverse materials: the policewoman, the song, and the social environment of the city. Can we hope for a translation, perhaps of this book and the first one in the series, some day?
