I enjoyed "Secret Prey" thoroughly. It divides into two separate parts. The first part is essentially a whodunit. I was entertained as my probable suspect, in classic whodunit fashion, was promptly murdered. After I got further into the book, however, I realized that the author cheated somewhat in this first section--even an astute reader will not be able to guess the killer. The second half of the book is much better. It gets into the mind of a smart, creepy killer, who can match strategy step-for-step with Lucas Davenport. This is reminiscent of the best of the "Prey" series, like "Eyes of Prey". I'd give this book a try, and stick with it.
