Immediate clarification for future potential readers: there noted "thriller" on the cover, but here the point of serial killer, or even police investigation. It should be closer to the first translation of the English word "thrill": thrill. This story is actually shiver, not by bombastic effects, but with its authentic side. The author takes us into a neighborhood story, a dark story, totally grounded in reality. So much so that you swallow this story butterflies in my stomach, because it describes how everyday can be a nightmare, through the fault of the suspicion and / or insanity. Everything is in the psychology of the characters in this simple but coherent story, written so both descriptive and moving.
