Detective Alex Cross is in love.
But his happiness is threatened by a series of chilling murders in Washington, D.C., murders with a pattern so twisted, it leaves investigators reeling.
Cross’s ingenious pursuit of the killer produces a suspect – a British diplomat named Geoffrey Shafer. But proving that Shafer is the murderer becomes a potentially deadly task.
As the diplomat engages in a brilliant series of surprising countermoves, in and out of the courtroom, Alex and his fiancee become hopelessly entangled with the most memorable nemesis Alex Cross has ever faced.
