Feedback Loop

When Foggy Point's beloved radio host collapses on air during KFOG's 50th anniversary broadcast, the official cause of death is simple: cardiac arrest from a pacemaker malfunction.

Case closed.

Except Elias "Coda" Cody heard something no one else could.

A retired Navy sonarman with hearing that defies medical science, Coda picked up an impossible frequency buried in the broadcast - a deliberate, lethal tone designed to kill. Now, with a tenacious young hacker, an eccentric antique dealer with a PhD-level knowledge of radio technology, and a small-town cop willing to trust his instincts, Coda has twenty-four hours to prove that Hal Morse was murdered before the case is closed for good.
The trail leads from a concrete bunker of a radio station on the Pacific Northwest waterfront to the sleek offices of a corporate media giant that will stop at nothing to acquire what it wants. But as Coda and his team get closer to the truth, the killer's signal finds a new target - and this time, the weapon is already in place.
In a town where fog hides everything and radio waves carry secrets, only a man who can hear what others can't has a chance of finding a murderer who kills without leaving a mark.

Feedback Loop is the second book in the Second Fret Mystery series.
