I'm a half-baked forensic examiner whose only redeeming quality is the ability to understand animals. The crime scene is inside a lavish villa. The lady of the house lies dead on the floor with a blunt-force injury to the back of her head so deep that her bone is visible. The safe has been pried open, and a million dollars in cash has vanished without a trace. Clear shoe prints mark the backyard wall, evidence that someone has climbed over it. "This one's clear as day. This is a textbook robbery-homicide. The suspect is likely a young male, around six feet tall, has a prior theft record, and knows how to cover his tracks. Check the surveillance footage in the area and look into places where he might've moved the stolen cash." The director of the forensic science center, Egbert Woodward, has been in the profession for three decades and is a widely respected authority. The officers at the scene nod in unison and begin taking notes. I'm the only one who stares at the 30 flies circling the ceiling for a full 3 minutes before taking a step forward and piping up, "Dr. Woodward, this isn't a robbery-homicide. It's a crime of passion. The murderer is the victim's husband!"
