Antonia Scott has an unusually gifted forensic mind. She’s the lynchpin of a top-secret project, Red Queen, created to work across borders to solve the most devious and dangerous crimes, those that are beyond the skills of the regular police.

But the Red Queen project is under attack on all fronts. Across Europe, its agents are murdering each other, and long-resolved cases from the past are rearing their deadly heads again. At the centre of it all is the mysterious and dangerous Mr White.

Jon Gutiérrez, Antonia’s protector and the only person she trusts, has been kidnapped. With Jon’s life at stake, Mr White gives Antonia a seemingly innocuous challenge: solve three crimes and bring the perpetrators to justice.

The only way to keep Jon alive is to play Mr White’s game, but can Antonia win when she can only see part of the board?
