FBI Special Agent Griffin Hammersmith, last seen in Backfire, has been recruited by Dillon Savich to join his unit in Washington, D.C. Savich sees something special in Hammersmith, an almost preternatural instinct for tracking criminals. While on his way to D.C., Hammersmith plans to visit his sister, Delsey, a student at Stanislaus School of Music in Maestro, Virginia. Before he arrives, he gets a phone call that Delsey was found naked, unconscious, and covered with blood after a wild party. The blood isn't hers—so who does it belong to?

Meanwhile, back in D.C., Savich and Sherlock have their hands full when the grandson of former chairman of the Federal Reserve Bank is found murdered, every bone in his body broken, and frozen at the foot of the Lincoln Memorial.

Was Savich right—is Griffin gifted with a unique ability to "see" how criminals think? And will he figure out who was behind the attempt on Delsey's life—before it's too late?

上次在《Backfire》一書中出現的美國聯邦調查局特務葛立分‧漢門史密斯這次受到狄倫‧沙維奇的招募，加入他在華盛頓特區的分隊。沙維奇看中漢門史密斯的獨特之處──追蹤犯人的超人直覺。在前往華盛頓的路上，漢門史密斯計畫要拜訪他的妹妹黛爾西，她現在就讀於維吉尼亞州的斯坦尼斯勒斯音樂學校。抵達學校前，他卻接到電話表示黛爾西在瘋狂派對之後被人發現全身赤裸，身上沾滿了血跡且不省人事。然而這血跡不是她的，那會是誰的？

同時，在華盛頓，沙維奇和夏洛克因聯邦儲備銀行前總裁的孫子遭到謀殺正忙得不可開交，屍體的每根骨頭皆斷裂，僵直在林肯紀念碑下。

沙維奇是對的嗎？葛立分是否真的有特殊能力可以看見兇嫌的想法？他來得及找出企圖對黛爾西不利的幕後黑手嗎？
