The so personal paw Franck Thilliez course omnipresent in this novel very interesting theme: past experiences and definitely coming around dementia and neurosurgery. A hot topic in the light of scientific advances. The meeting of Lucie and Sharko is, in my opinion, much more anecdotal: the rescue of two souls in emotional distress and the simulation of their respective characters perfectly glue with the theme of this thriller. I find that the chapters were unnecessary or could be shorter, including travel Sharko in Egypt, a trip that ultimately did, that anecdotal. Otherwise, this is a cleverly constructed and well written novel. Would recommend to any lover of good thriller.
