Brother Benhamou is a member of a lodge in Versailles. As I mentioned in the book,the notion of Masonic recognition is a sticky one, especially in the US where such issues can be hotly debated. Philippe's lodge is under the jurisdiction of the Grande Loge de France, the 2nd largest Grand Lodge in the country. Unfortunately, all mainstream US Grand Lodges recognize the Grande Loge Nationale Française - which is smaller in terms of membership. The upshot of this seemingly arcane discussion is that I can not sit in the same lodge with the co-author of my own book.
And if that isn't madness, I don't know what is.
