In this book a British spy named Hemfer working in the early 1700s tells of disguising himself as a Muslim and infiltrating the Ottoman Empire with the goal of weakening it to destroy Islam once and for all by promoting alcohol and fornication. But his first step is to promote innovation and disorder in Islam by creating Wahabism. Wahabism which is to gain credibility by being on the surface morally strict. For this purpose he enlists a gallable hot-headed young Iraqi in Basra named Muhammad Ibn Abdul-A'Wahab. Hemfer corrupts and flatters Abdul-A'Wahab until the man is willing to found his own sect.
