A bitterly cold night offers up a body turned blue--not frozen, but swinging from a rope in a dank basement. The dead teen seems like a clear case of suicide, but Detective Steve Carella and Lieutenant Peter Byrnes find a few facts out of place, and an autopsy confirms their suspicions. The boy hadn't hung himself but OD'd on heroin before an unknown companion strung him up to hide the true cause of death. The revelation dredges up enough muck to muddy the waters of what should've been an open-and-shut case. To find the answers to a life gone off the rails, Carella and Byrnes face a deep slog into the community of users and pushers--but a grim phone call discloses that very community already has its claws in a cop's son. A new pusher is staking a claim right under the 87th Precinct's noses, and it's up to Carella and Byrnes to snag the viper before it poisons their whole lives.
