Lincoln Rhyme and his partner Amelia Sachs are called to the case. They have tracked down some of the world's most brilliant criminals, but this hunt is posing more questions than answers. Where will their prey strike next? What is the historic secret he's desperate to protect? And how can anyone catch a killer who leaves no trace? Sachs will have to search a crime scene that's over 140 years old and attempt to uncover a secret that that may strike at the heart of the United States constitution . . .
