Try The Templars by Peirs Paul Read. It is timely considering that it deals with the crusades, Middle East, Muslims, etc. But it also provides alot of information not only about the Templars, but about the relationship between the Muslim peoples and Europeans. In fact, it describes alliances between the two when it served their repsective purposes, something that surprised me.
