From Understanding Behavior as Children, to Exploring Why We Cross the Line
Exploring the darker side of human behavior—one story at a time
About Bill Corbett
Welcome to the Darker Side of Bill Corbett
You may know me from somewhere else.
For more than three decades, I wrote, spoke, taught, and broadcast about parenting, relationships, and human behavior. But my fascination with why people do what they do began long before that.
I earned my degree in clinical psychology, where one area particularly captured my attention: abnormal psychology.
I was fascinated by the darker side of human behavior. Why do otherwise ordinary people sometimes make terrible choices? What happens inside the mind in the moments before someone crosses a line they can never uncross? And how does a person end up looking back at something they've done and asking: “What was I thinking?”
For years, I explored human behavior from the parenting and relationship side of the equation. Now I'm exploring the other side.
The Ovulation Murders is my first psychological thriller—and the beginning of a new series exploring relationships, obsession, secrets, impulsive behavior, and those unsettling moments when seemingly ordinary people do things no one imagined they were capable of doing.
If you enjoy psychological thrillers that take you inside relationships, inside people's secrets, and occasionally inside minds you probably wouldn't want to visit alone... Welcome.
