This book was developed after years of teaching interviewing skills to thousands of investigators, inspectors, police officers, and other people who need to learn information from others. The book teaches a technique that uses inherent skills to maximize success in obtaining information. The key to interviewing is versatility in the interviewer to adapt to the person being interviewed. Our biggest enemy is our ego and our greatest asset is our ability to show empathy for the unlovable. This book sets a continuum for success. If we only had to interview people we liked, it would be an easy task. Unfortunately, we often have to interview those we don't like.
