Together they must work in finding the bad guys. Only they find the heroine too easily. I love the work ethic of these characters. They needed to build of their trust of each other and build a budding partnership. As the investigation goes further, they find they like each other more than they want to admit. The combination of crime, suspense, and romance made this an unforgettable tale. It is addictive. Going after the bad guys is typical work, but going after their unknown enemy makes it that much harder. Overall, Lynn H. Blackburn creates another engaging and thrilling novel.
