A long weekend in the Poconos is cut short when Sherlock and Savich are helicoptered back to Washington to lead the investigation into the brutal murder of a Supreme Court Justice. Savich allows Callie Markham, an investigative reporter for The Washington Post, to partner with local Metro Police liaison Ben Raven, since she’s got the inside track - she’s the stepdaughter of the murdered justice. Despite Detective Raven’s unwillingness to have a civilian along, Callie Markham ends up riding shotgun to help look for her stepfather’s murderer. Within the next twenty-four hours, a Supreme Court law clerk is found murdered, the M.O. the same. Savich learns he must also solve a thirty-year-old crime after a psychic encounter with the murder victim, Samantha Barrister, who suddenly appears in front of his car and hysterically pleads for his help.
