The Silent Frequency of Prague
A Cold War Numbers Station Thriller

About this book:

Beneath the frozen streets of 1981 Prague, Milada Havlová spends her nights in a windowless basement, playing the same ghostly numbers broadcast to agents shivering behind the Iron Curtain. It's monotonous, dangerous work—one slip means the uranium mines of Jáchymov—until the night the static between the five-figure groups begins to pulse with a rhythm no ionosphere could produce. Someone is hiding a second transmission inside the State Security's own frequency. And the word it spells, in her own language, is *Návrat*. Return.

Her only colleague, Jan, has heard it too. His warning is a masterpiece of bureaucratic terror: log nothing, hear nothing, survive. But the signal is Czech, domestic, and impossibly close—coming from somewhere within the city's own rooftops. As Milada peels back layers of Cold War tradecraft, from dead drops on the Charles Bridge to the cipher machines of Bartolomějská Street, she realizes the broadcast isn't just a message. It's a summons. And the next voice on the frequency might be her own.

Atmospheric, technically precise, and taut with the paranoia of a surveillance state where even the airwaves are watched, *The Silent Frequency of Prague* is a spy thriller that doesn't just recreate the Cold War—it lets you hear it humming in the dark.
