When loyalty becomes a weapon, and secrets turn deadly.

MI5 Intelligence Officer Greg Travers thought his life couldn’t get any worse after losing his wife and unborn twins. He was wrong.

Dragged back from the abyss by duty, Travers exposes billionaire philanthropist Olga Devereux’s criminal empire and foiled her vengeful plot to assassinate a German politician. With Devereux behind bars, he’s ready to move on.

But when Devereux walks free after striking a deal with the former Home Secretary, Travers discovers the Cerberus File, a dossier of corruption reaching into the highest echelons of British power. Now protected by the very establishment she’s compromised. Devereux is orchestrating a campaign of terror that threatens to bring down the government itself.

As bombs explode across London and a biological weapon looms over the capital, Travers must navigate a labyrinth within his own organisation. Someone at MI5 is feeding information to the enemy. Trust no one. Question everything. Because in this game, the deadliest threats come from within.

From the sun-drenched shores of Jersey to the gothic ramparts of Elizabeth Castle, from the underground Nazi tunnels to the storm-tossed English Channel, Travers races against time to stop a thought-out revenge plot. But Devereux hasn’t forgotten that he killed her son, and she’s prepared to sacrifice thousands to make him pay.

Perfect for fans of Mick Herron, Charles Cumming, John le Carré and classic British espionage thrillers.

The second explosive instalment in the Greg Travers series.
