Red Warning — Matthew Quirk

Agent Sam Hudson tracks a Russian deep cover operative loose in the U.S. and a possible mole in the CIA days before a devastating attack on Washington D.C. in this adrenaline-fueled thriller from the author of The Night Agent and Hour of the Assassin.

For years CIA officer Sam Hudson has been hunting Konstantin, a Russian deep cover operative, responsible for several murders in the West -- and now he believes he's picked up his trail in Geneva. But just before a crucial meeting, the man he's trying to reach is ambushed, Sam's partner is killed, and he barely makes it out alive himself.

Back in the States, the bosses want him to drop his obsession with Konstantin, but Sam can't let a man who's killed so many slip away again. When he gets a mysterious call right before a bomb attack, Sam realizes Konstantin has followed him to the US -- and now it's personal. Teaming up with fellow CIA agent Emily Pierce, he sets out to find the mastermind who's evaded capture so many times. But every way he turns there are roadblocks, and he begins to wonder if Konstantin has some inside help.

With enemies potentially hiding in plain sight and the Russian threat looming ever larger, Sam must use all his training and nerve to find out what Konstantin is planning and bring him down -- before Konstantin sets the nation's capital ablaze.
