In line with the Tome1. Maxime Chattam fan, I was very disappointed in this diptych. The first one does not believe, it does not catch, only postcard Paris of the early 20th is interesting and really bad end, ridiculous. This tome2 starts well in one hangs then falls on anything with spiritualism, Egypt and its mummies and surprising revelations so they are not credible. I really hope Maxime Chattam returns with a thriller as he knows so well.
