Like a cat, she brings me the mangled bodies of her victims.

For her, it’s an act of love.

Eve Polastri and Oxana Vorontsova want a quiet life together in London. Moscow's spymasters have other plans. When an eighteen-year-old girl steps off a plane at Heathrow, claiming to be the daughter of the Duke of Albemarle, the couple are drawn into a game with no rules and no mercy.

The duke is a close friend of the king of England, but who is Polina Kuzmina? An innocent caught in the crossfire, or a weapon aimed at the heart of the British establishment? As the action moves from the shores of the Adriatic to a deadly final act at Balmoral Castle, Eve and Oxana have just days to unravel Moscow's plan.

Can they assemble the pieces in time to avert national catastrophe? Can they outwit the killers determined to stop them?
