Lord Alexander Hawke is used to going after big game, but his pursuit of a mysterious figure code-named Warmonger brings him up against his most deadly foe—Vladimir Putin—in the latest entry in this New York Times bestselling series.

Lord Alexander Hawke’s hunt for the Warmonger—a shadowy figure orchestrating chaos across the globe—is put on hold so that he may undertake an urgent mission for the Crown. His assignment: Travel to Russia, escorting the lovely Dr. Ariadne Silk; confront his archnemesis, Vladimir Putin; and recover a secret document that threatens to shake the British monarchy to its core.

While Hawke makes a perilous journey across Europe, his good friend Ambrose Congreve’s routine investigation of a bizarre murder takes a deadly turn, pulling him into a cat-and-mouse game with Silence, a cold-blooded assassin who may be targeting Hawke himself.

Hawke will soon discover that he is a pawn in the Warmonger’s Byzantine plot to bring the world to the brink of total war and resurrect a fallen empire.
