This novel could have made much more of interest taking into account the originality of the outset of the investigation, namely the confessions of a woman on her deathbed, and the different characters. Indeed collaboration between a homosexual police officer and a psychologist could offer hope for an investigation and most sought denouement. Unfortunately the multiplication of secondary characters make the story hard to follow, and the progress of investigations seems, on the contrary, too easy. Yet this book is not unpleasant to read and can help you have a good time. Good reading.
