All of Jeffrey Deavers books are thoroughly enjoyable and this one is no exception. Typically the plot twists and turns quickly. Although I have read most of his books and am used to his style he does still catch me out. Deavers attention to detail is remarkable, whether it is accurate or not isn't the point, the point is he is convincing. This book focuses on 'data mining' a company which collects and sells detailed information on the public for marketing and sales opportunities. Deaver doesnt judge just simply presents the argument for and against; police catching criminals vs invasion of privacy. But what makes this book so good is the interesting and enduring characters, especially the leading two Lincoln Rhyme and Amelia Sachs. Their relationship has developed and with each book we learn a little bit more about them. Enjoy.
