In the fourth installment of the Inspector Zoë Janssen Thrillers, Zoë finds herself facing her toughest—and potentially most dangerous—case yet. Summoned to England by escaped prisoner and violent serial killer Sven van der Linde as part of his deadly, cryptic game, Zoë is forced to try to solve his puzzles as they're unveiled to prevent any new victims. As the stakes increase and the consequences become more personal than she ever imagined, Zoë's confidence begins to crumble. And even though she's come to rely on the strengths of her friends and colleagues, she realizes only she can, and should, play this deadly game.
