I didn't know we were playing a game.
But of course we are. . . .
An expert in animal behavior with a brilliant analytical mind, charismatic Oxford professor James Fieldhead needs a willing subject to test a groundbreaking device that may offer the key to understanding human emotions. Encouraged by Cara, his seductive new girlfriend, Ben Ashurst agrees to participate in the study, honored to be part of the first crucial stage of life-changing research. With a luxury resort on a pristine beach in Kenya as the site of the experiment, and Cara along for the ride, it seems a perfect way to spend the winter holiday. Yet beneath the surface of a sunny paradise awaits something cold and ruthless.
As the experiment veers from abstract theory into terrifying reality, Ben finds there is no one he can confide in. Impetuous Cara is intimate one night, then distant the next, forcing Ben to wonder where her true allegiances lie.
Snared in a masterfully crafted labyrinth of cunning, in which each step can lead closer to a solution or deeper into chaos, Ben scrambles to learn why he was chosen for this project. Fieldhead's obsession with game theory suggests a possible course of action. But every time Ben thinks he has discovered the winning move, he finds another level of deception, another betrayal of his trust.
Moving from the sheltered colleges of Oxford to the magnificent landscape of Kenya, The Mind Game is full of intriguing characters and stunning plot twists. Justwhen you think you have mastered The Mind Game, you might just be mistaken . . . . From the Hardcover edition.
