In the late 21st century, on the streets of New York City, a street sleeper is found murdered, his diseased heart removed with surgical precision. His death would typically drop to the bottom of a list of senseless and inexplicable killings, but Lieutenant Dallas, who "would stand for the dead and the living," is not about to let that happen. When her research uncovers similar crimes in several cities that were dropped under mysterious circumstances, Dallas knows she's facing a killer cruel enough to prey on the weakest in society and powerful enough to conspire an extensive coverup.
To complicate matters further, Dallas faces an equally troubling threat to her career when she's linked to the death of a fellow cop. Now she must fight to restore her good name as well as track down the killer.
