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.

Tough guy Thomas Beckett is a US Marine working in the Panamanian jungle. His job is to seek out rebels and remove them using his sniper skills. Beckett is notorious for losing his partners on such missions. This time he's accompanied by crack marksman Richard Miller, who's more of an office-type. Together they plan to seek out an important rebel leader, whilst avoiding a rogue marksman who frequents this part of the jungle.
