When the body of a young woman is discovered in Central Park, the clock begins ticking for Assistant DA Alex Cooper and Detectives Mike Chapman and Mercer Wallace to find the killer who has breached this haven in the middle of New York City. Is the body found in the lake, under the unseeing gaze of the Bethesda angel, the first victim of a deranged psychopath, or is the case connected to other missing girls and women in years past whose remains have never been found? Just as the trio gets their first lead, the investigation is almost derailed when Mike and Alex become embroiled in a scandal. As Alex attempts to fight the accusations leveled against her and Mike, she follows clues that range from the park's most buried -- literally -- secrets all the way to the majestic Dakota, which has experienced its own share of tragedies. When another young woman is attacked in the park, a new question arises: is this enormous urban park a sanctuary -- as it seems to the thousands of New Yorkers and tourists who fill it every day -- or is it a hunting ground for a killer with a twisted mind?
