The Pawn by Steven James (2007)

It's a crime thriller/mystery. It's a novel about an FBI agent who specializes in how time and geography help to solve the crimes. The criminal in this book is a serial killer (hence a few gory/messy parts). It is published by a Christian publisher but the book tends toward the philosophy that people will come to know God more by actions than by words (and outright evangelistic sections). The books has great plot twists and the quality of the characters is very high. The multi-layers to the plot and problems are definitely what makes it good. It's worth recommending.
