A nurse at the Baltimore State Hospital for the Criminally Insane is brutally murdered by a patient, Dr. Abel Gideon, in a manner reminiscent of the "Chesapeake Ripper", who hasn't committed a murder in two years, the same number of years Gideon has been incarcerated. While Graham tries to discover whether Gideon truly is the Ripper, Crawford receives a phone call, apparently from the real Ripper, who plays the recorded voice of Miriam Lass, a trainee Crawford had consulting on the Chesapeake Ripper case two years previously when she suddenly disappeared.
