A Person of Interest (S02E23)

In a continuation of a previous episode, the season finale finds Detectives Goren (Vincent D'Onofrio) and Eames (Kathryn Erbe) probing the murder of a former Air Force nurse - but the discovery of anthrax nearby intensifies the search and pushes Goren into the headlines when he is blamed for a suspicious scientist's suicide. However, the investigation turns even more byzantine when a disgraced Goren discovers a former cunning adversary (guest star Olivia d'Abo) might be involved in those deaths and more. (iTunes)
