?The process of investigation is relevant for a wide array of security professionalsboth in the private and public sectors, including corporate investigators, attorneys, loss prevention specialists, and law enforcement personnel.

The Process of Investigation sets out to address the needs of today�s private sector investigative professionals. Through 24 chapters, the authors provide a practical guide to conducting comprehensive investigations. Five main sections take the reader through fundamentals, methods, building a case, applying strategies, and using technology and other specialized investigative techniques. Among the topics explored in detail are qualities of the investigator, surveillance, interviews, report writing, and targeted violence.

The book has something interesting for all readers who work with investigations or just want to know more about the art and science. There is a lot of information for people new to the investigative area, and there is also something for the more experienced practitioner. Examples from real investigations help readers place the theory into a practical context. A point well made is that investigative success often comes from �applying common sense and uncommon persistence.�

Although the book takes an American view of investigation, most of the material is applicable for international use, and it should find a well-deserved place on the investigative professional�s bookshelf.
