Books In Sheep's Clothing: Understanding and Dealing with Manipulative People by Dr. George K. Simon Ph.D. (Author)

"In Sheep's Clothing: Understanding and Dealing with Manipulative People" by Dr. George K. Simon Jr. is a definitive guide to recognizing and countering manipulative behavior. The book explains that manipulators often use covert aggression—a subtle, indirect method of control through tactics like guilt-tripping, shaming, lying, denial, and playing the victim—to attain power and get their way without overt confrontation.

Simon highlights that manipulators have impaired conscience and lack respect for others’ feelings or rights, making their tactics especially harmful. The book details how manipulators exploit emotional vulnerabilities such as low self-confidence or over-conscientiousness and how victims get trapped in manipulation cycles through intermittent rewards, termed the "Slot Machine Syndrome."
