When does Cagney & Lacey return?

The pilot movie had Loretta Swit in the role of Christine Cagney, while the first six episodes had Meg Foster. When the show was revived for a full-season run, Gless portrayed the role for six consecutive years. Each year one of the two lead actresses won the Emmy for Best Lead Actress in a Drama. The series is set in a fictionalized version of Manhattan's 14th Precinct.
