When does The Hardy Boys/Nancy Drew Mysteries return?

The Hardy Boys/Nancy Drew Mysteries was an American television mystery series based on the Hardy Boys and Nancy Drew juvenile novels. Parker Stevenson and Shaun Cassidy starred as amateur detective brothers Frank and Joe Hardy, respectively, while Pamela Sue Martin (later Janet Louise Johnson) starred as Nancy Drew. The series alternated between episodes that featured the Hardys and episodes featuring Drew in its first season. As the series progressed, the two storylines crossed over, and the Nancy Drew character was drastically reduced. Midway through the series was canceled by ABC.
