The police turn up only one clue: a mysterious rhyme signed "Jack and Jill" promising that this is just the beginning. Meanwhile, homicide detective Alex Cross is called to a murder scene only blocks from his house, far from the corridors of power where he spends his days. The victim: a beautiful little girl, savagely beaten-and deposited in front of the elementary school Cross's son attends.Could there be a connection between the two murders? As Cross tries to put the pieces together, the killer-or killers-strike again. And again. No one in Washington is safe-not children, not politicians, not even the President of the United States. Only Cross has the skills and the courage to crack the case-but will he discover the truth in time?
