Hardy Boys/Nancy Drew Mysteries was a television series that aired on ABC between 1977 and 1979 and that consisted of 44 hour-long episodes. During the first two seasons, the focus of each episode would alternate between the Hardy Boys and Nancy Drew (the three would also team up for several joint episodes in the second season); the final season aired as The Hardy Boys Mysteries. Shaun Cassidy and Parker Stevenson portrayed Joe and Frank Hardy, respectively, in all three seasons. Pamela Sue Martin starred initially as Nancy Drew, but left the series midway through the second season, at which point she was replaced by Janet Louise Johnson. Glen A. Larson, who developed the series, was the executive producer. All three seasons have been released on DVD.
