The body is found at 3:47 in the morning.

Daniel Varga - audio engineer, paranormal investigator, host of the podcast The Dead Frequency - is seated in the broadcast chair of an abandoned 1940s radio station. Headphones on. Hands in his lap, palms up. Eyes open. Connected to a console that has had no power for thirty-seven years.

The ON AIR light is glowing.

Detective Nora Voss has worked homicides long enough to know that the cases that start without explanation are the ones that change you. But nothing in her career has prepared her for what the Meridian Building holds: a history of deaths no one could explain, a signal no instrument can source, and a frequency that has sat silent on the AM dial since 1987 - silent, that is, to everyone except the people who have died listening to it.

As Nora digs deeper, she uncovers the building's dark blueprint: a physicist named George Meridian who designed the studio in 1940 not to broadcast, but to receive - to pull in a signal that ordinary equipment could never detect. A signal that has been transmitting since before anyone alive can remember. A signal that doesn't just carry voices. It carries the dead.

Three men. Three generations. The same chair. The same headphones. The same expression on their faces when they were found - not fear, but the look of someone who has just understood something enormous, and understood it too late.

Nora doesn't believe in ghosts. But she believes in patterns. And the pattern the Meridian Building has been drawing for eighty years is leading somewhere she isn't sure any living person was built to go.

Some frequencies were never meant to be heard. Some signals never stop transmitting. And some doors, once opened, cannot be closed.

DEAD FREQUENCY is a propulsive, atmospheric mystery thriller for fans of The Silent Patient, Mexican Gothic, and The Mister - where the line between detective fiction and the uncanny dissolves one transmission at a time.
