Chosen Prey

I liked this book written by John Sandford. James Qatar is a history professor interested in photography. He likes to secretly take pictures of women and then uses his computer to combine their faces with seductive bodies he finds on the internet. But when one of the women discovers his secret he becomes more stimulated by committing murder. It is up to detective Lucas Davenport to find the suspect and develop a compelling case against him. This is the 12th novel in the series.
