The diner is empty at dawn.

Coffee still warm. Plates half-eaten. Chairs pulled back as if every patron stood at the same moment and simply ceased to exist. No signs of struggle. No blood. Nothing broken.

Just a cassette tape in the kitchen, labelled PLAY ME.

Sheriff Callie Hart has protected Harrowfield her entire career. She knows every face, every routine, every locked door in a town where nothing changes. But the voice on the tape knows things about her childhood that no stranger should, the colour of her bedroom wallpaper, the arguments her parents had on Thursday nights, the word her father said in his sleep the summer a boy vanished from Camp Briarwood.

The summer her father sealed the case file and never spoke of it again.

Now residents are disappearing from locked rooms. Each scene is pristine and staged. Each holds a playing card. The cards correspond to roles in a children’s game once played at the camp, a game of secret identities and elimination called King’s Table. Someone is replaying it, round by round, and the pattern leads back to a circle of chairs in a cabin in the woods and the night seven adults decided that silence was easier than the truth.

As the game escalates, Callie confronts a choice that mirrors her father’s: protect the family legacy, or expose the cover-up that made everything possible. The killer is patient, methodical, and has been inside the walls of her town for years. He doesn’t want blood. He wants a reckoning.

And the final round requires the Sheriff to sit at the table.

PLAY ME AT THE DINER is a dark, psychologically immersive serial killer thriller about inherited guilt, institutional failure, and the games we play with the people we’re supposed to protect. For readers of Chris Carter, Karin Slaughter, and Robert Dugoni.
