Mary Ellen O’Toole is my hero! In Dangerous Instincts she offers sound advice and fascinating examples gleaned from her long career in the Behavioral Analysis Unit of the FBI. This book will save many lives—including, quite possibly, your own. Whether the knowledge you find herein saves you from a con man, a rapist, a thief, a killer, or just a miserable marriage, this is a classic, valuable book. I recommend it highly to all my family, friends, and readers.”—Ann Rule, author of THE STRANGER BESIDE ME
“A masterful and compelling primer on survival in a world in which people are not always what we think them to be. Dr. O’Toole’s deep understanding of the nature and implications of psychopathy. . . is particularly impressive, and shared by only a few other criminal investigators. This is an important and well-written book on topics of concern to everyone. A great read, highly recommended.”—Robert Hare, Ph.D., author of WITHOUT CONSCIENCE
“In this absorbing read, [O’Toole] discusses why people trusted Bernie Madoff and Ted Bundy and dissects online dating responses and typical blind spots. The author helps readers analyze their decision-making patterns and provides a guide for helping them to assess and mitigate risk. O’Toole’s book will provide insight to everyone, but it’s particularly helpful for women living alone, parents concerned about their children’s safety, or employers worried about perplexing employee behavior.”—Library Journal
