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.

Four complete practice tests which follow the format of the revised Cambridge First Certificate English examination.
