Eve's life hangs in the balance. The twins' pursuers are closing in. For Adam, time is fast running out… While Eve recovers from surgery, the monster known as Grendel kidnaps her and disappears. To save his sister, Adam must obtain and make use of the tracker he and Eve had planned to destroy. But without her by his side, can he hope to get past the mighty organisation's defence mechanisms? Knowing it is his only chance, Adam launches a one-man assault against the device's location, and at first, it appears nothing can stand in his way. But as he grows closer to his goal, it becomes clear his biggest challenge will not be physical, but moral. Adam might be able to save his sister, but will it come at too great a cost to his already fractured humanity? Cat and Mouse is the third of six novellas in the gripping Adam and Eve thriller series from Mark Ayre. Perfect for fans of Dean Koontz's Nameless, Harlan Coben and James Patterson
