I discovered this new author, and what a surprise !! However, I am a veteran of thrillers and even some "musts" said writers have disappointed me. The serial killer is a subject widely used by writers but it differs because there is in the mind of serial killer. The various parallel characters are very well described and their psychology which we can understand them. Book eaten in 3 days not let go until the final denouement. This is the first novel by Celine Dejean and I hate to discover the second.
