Spooks

Harry activates his first sleeper agent, university professor Fred Roberts for "Operation Flytrap". Section D detonates a bomb in an abandoned council house and spreads a rumour that two terrorists died while tampering with hypothetical red mercury created by Roberts to develop nuclear weapons. Section D proceed to ruin Roberts's life by arresting him, make his family leave him and put him in debt to make any potential buyers believe he would be selling the red mercury for financial security. He is later approached by Lawrence Sayle of Al?F Command, a Kyrgyzstan-based terrorist group. Over time, Tom becomes more concerned with Roberts's mental state. He ultimately undergoes an "exploding conscience" and sabotages the operation by attempting to take Roberts to his family. However, he is stopped and is decommissioned from MI5 as a result. The operation continues and MI5 are able to arrest Sayle and kill his accomplices who attempt to kill Roberts's family. Meanwhile, Zoe Reynolds starts a relationship with photographer Will North.
