As a genetic criminologist and the daughter of an Irish mobster, Billie Quinn is no stranger to crime, and as far as she's concerned, those arrested are usually guilty. But when she and her boss are asked to help free a man wrongly convicted of murder, she believes he's innocent. When new DNA testing procedures prove it, the real criminal gets nervous, and Billie and friends soon find themselves in danger. Trace of Innocence (4), by Erica Orloff, is a well-researched and interesting novel that will hold reader attention from beginning to end. Orloff's attention to detail is apparent in the amount of information included in the story. Crime novel buffs, especially, will love this book.
