Detective Margot Phalen knows the mind of a serial killer better than most. She learned from the worst: her father, Ed Finch.

When bodies keep appearing in the tranquil Muir Woods, California, and a woman is killed in Chinatown, Margot begins to realize these are no ordinary homicides. The eerie similarities to her infamous father's crimes send chills down her spine. But Ed’s been behind bars for years now – surely he couldn’t mastermind this from his cell, could he?

As evidence mounts – a bloodied image of Ed’s first target found in a victim’s home, stab wounds that match Ed’s trademark pattern – Margot uncovers a sinister obsession that hits far too close to home. She must use all her skills to outwit a killer who seems to know her history better than she does.

To solve this case, she’ll need to confront the dark secrets of her past, and face her worst fear: that she may be more like her father than she ever dared imagine.

The Killer Instinct is a gripping crime thriller that will keep you turning the pages. Fans of Karin Slaughter, Michael Connelly and Tana French won’t want to miss this unforgettable series.
