The conspiracy just continues to grow on "Person of Interest" - which returns to air on March 10th following a winter hiatus. Michael Emerson plays Harold Finch, a quirky, reclusive billionaire who developed a machine that can isolate the social security numbers of people with either premeditated homicidal intent or who will be homicide victims. In order to prevent crimes identified by the machine, he recruits John Reese, a former CIA agent. "The roadmap for this season has been us being forced out our habits and our old base of operations. We've been made to go underground so we are now like an invisible cell of people that can't really show their faces because Samaritan wants them dead. So we have to use a different set of resources, a difference sense of improvisation to keep after our mission." According to Emerson, his character designed the machine after the 9/11 attacks that was meant to predict future terrorist attacks. But, he discovered, the Machine also had prior knowledge of ordinary crimes, which prompted the team to help people in peril. "It was bad enough. It was always a suicide mission and now that they're playing their chess game, if you will, on more layers than one the chances of being tripped up or caught or killed are so much greater. It's hard to find safety.　So I think he's constantly improvising, trying to find a way to hold on to the mission, which is all they have, it seems like." In the first part of this season, one of Finch's teammates Sameen Shaw seems to be killed off. But, Emerson admits that her fate is unknown. "Her character's an interesting one and she's so wonderful playing it and she's good at it. I think there are some regular characters and some as yet unseen characters that are going to come in and take up some of the slack and take the show maybe in some slightly new directions." The new episode of "Person Of Interest" airs on this Tuesday, March 10th.
