Tyne Daly (Christy) played Detective Mary Beth Lacey. Sharon Gless, (The trials of Rosie O"Neill) was Detective Christine Cagney. This was a show about two women who worked together and became good friends outside their job. Harvey Lacey,Tony LaTorre, was a nice and understanding husband.This show was really well done and we enjoyed watching it. It is always good to see women playing that type of role. There is one episode that stuck with me. It was about Hispanic illegal aliens in the United States living in horrible conditions, even in the attic of a building. They were chasing them and purposefully missed them, by saying: "there is nobody here." That was a nice episode where they showed a lot of compassion.
