When Lorànt Deutsch will pull the bells to discover the remains of the walls of Philippe-Auguste, I adore! This makes the man and now infinitely sympathetic, and the book is readable with great pleasure. But let us be clear, this is not a historian, and this book "general public" quite conceals amateurism and approximations. If only his reading could serve as a "springboard" to give many readers want to discover the work of the "real" historians of Paris, which are legion, it would already not so bad. For that alone, we could say bravo!
