This isn't your regular whodunnit or even a psychological thriller. It's a straightforward murder case where the reader knows what has happened and reads the book wondering if detective K is capable of solving it.
Safe in this knowledge, the reader smirks, amused that the detective K is taking too much time. And then, there comes something that makes the reader sit straight and pay more attention. The reader realizes that only the physicist, the famous Detective Gaelio, got it right, and that doesn't match with what's in the reader's mind.
The writing was to the point and neat, though it still slowed down my reading speed. Deleted one star for that.
