Private investigator Deklan Falls has fought hard to leave his past behind. Once a corrupt cop with blood on his hands, Deklan rebuilt his life in Oldtowne. He's sober. He's married. His detective agency is thriving, and for the first time in years, the future looks brighter than the past.
Then an old friend arrives in the middle of the night.
Ted Hollister spent decades buried inside the U.S. intelligence community, and he's terrified. He claims a long-forgotten Cold War project called Echo Protocol has been reactivated, a secret program capable of turning ordinary people into ruthless killers through coded radio transmissions. The government insists the project died decades ago.
Ted knows it didn't.
When he's murdered hours later, Deklan inherits a cache of classified files, and a mystery someone is willing to kill to keep buried.
As gruesome murder-suicides spread across the country, Deklan uncovers a terrifying pattern. Innocent people are receiving an unseen signal, committing horrific acts of violence, and then taking their own lives, leaving behind no motive, no explanation, and no one to question.
The deeper Deklan digs, the more powerful his enemies become. Shadowy corporations, private military contractors, and ghosts from the Cold War begin closing in. Every answer puts another target on his back, and on everyone he loves.
Because Echo Protocol was never just an experiment. It was a weapon, and someone has decided it's time to use it again.
Echo Protocol is the explosive fifth novel in the acclaimed Deklan Falls thriller series, a gritty blend of noir detective fiction, espionage, conspiracy thriller, and relentless action. Perfect for readers of Lee Child, Michael Connelly, Robert Crais, and Gregg Hurwitz, it's a pulse-pounding story of secrets that should have stayed buried... and one detective determined to expose them, no matter the cost.
