"Paramedic Billy King is no stranger to emergency calls. But when he gets home to find police ramming down his door, his world starts fracturing along with it. They'd received an anonymous call claiming a woman's body was in the flat and, sure enough, his wife - an artist - is found alive but bleeding heavily in their bathroom. She survives and says she'd just slipped on some wet tiles - but her behavior becomes increasingly erratic and by the time she sets off for an artists' retreat a few weeks later, Billy's convinced she's lying about where she's going - and with whom. It's only when he starts following his wife that he makes a terrible realization. He's not the only one observing her. And when he discovers drawings of his wife's mutilated body, he desperately hopes he can reach her before the horrors of the sketchbook become a reality."--Publisher.
