I was able to finish another book, yesterday, that being The Templar by P. C. Doherty. I've read a lot of the author's works, and he's generally very good at setting the scene, and good at setting up a mystery, but not as good at defining his characters. In this one, the milieu is well-laid-out, but the mystery is nearly ignored, and the characters are nearly interchangeable. Not horrible, not his best.
Oh, and it's about the First Crusade, and the assault on Jerusalem.
