When a young doctor, Maslow Atkins, goes for a quick run in Central Park and doesn't come back, April's usually flawless cop instincts tell her that he is alive. She orders a massive search using the city's best K-9 tracking unit, though it means going outside her jurisdiction and outside her authority. It takes the brutal murder of a witness for April's hunch to be believed... yet she still finds herself no closer to unraveling the lethal tangle of family secrets that obscures the most disturbing crime she has ever faced.
