Taking as an excuse the analysis of a Beethoven's lock of hair, "Beethoven's hair" is the biography of the musician, but also of all these people who owned the lock and the History through which it traveled.
It is a very emotive story, full of hypotheses and subjective novelization mixed with facts and data.
But in spite of all that, it is not a pleasant reading.
The text is full of exceedingly complex subordinate sentences (some of them 9 lines long with commas, dashes and additional comments,) furthermore the author repeats the same sentences, comments and stories once and again. In every chapter he sends us back and forth, and back again, retaking the tale from where he left us pages ago to talk about a friend of the brother of the neighbor of someone who passed by the current owner of the lock... Did he review his writing before sending it to the editor? Did the editor really read the book?
Very poor writing, really.
On the other hand, it's a lovely story to know and a good way to appreciate the little facts that make single lives special ones.
I really loved the story (all the different stories that compose this book), the idea to explain it through a lock of hair, the way to alternate Beethoven's biography with the ones who owned the lock and the progress of the investigation, the emotions, the music sensibility, and the serendipity of all that... and only based on this I would surely give a better rating (in fact, I'm giving a very high rating for my own standards). But I felt dizzy reading it, and if I weren't on holidays, I would have probably abandoned the reading.
The same data in other hands would have made a five stars book.
