Talk about a well-deserved promotion: Missy Peregrym is trading in her Rookie Blue uniform for a spot at the F.B.I. Peregrym has been tapped to star in the Dick Wolf-created series, which - as the title suggests - focuses on the men and women in the New York office of the Federal Bureau of Investigation, our sister site Deadline reports. Peregrym will play Special Agent Maggie Bell, a highly protective and deeply committed Midwest native whose family has been in law enforcement for generations.
