Twenty years ago, Alton Turner Blackwood murdered four families before a teenage boy ended his reign of terror. That boy grew up to be homicide detective John Calvino.
Now, a new killer is copying Blackwood’s crimes in chilling, exact detail—and John knows his own family is next.
As the past claws its way into the present, John begins to question everything he believes. Logic says ghosts don’t exist. But the darkness stalking his wife and children feels far too personal, far too intimate, and far too real.
To save the people he loves, John must face the impossible truth: evil doesn’t always die.
What the Night Knows is a #1 New York Times bestseller that blends supernatural suspense and psychological horror with classic Dean Koontz chills—and includes the bonus novella Darkness Under the Sun.
