Quadripeligic ex-cop Lincoln Rhyme was looking forward to his assisted suicide when he got the news: some sicko was abducting people in a taxi and leaving them to die in particularly sadistic ways. With time counting down between each abduction and possible death, Rhyme recruits rather-unwilling Amelia Donaghy, haunted by her cop father's suicide and thinking she's next, into working the crime scenes to track down the killer.
