"Dr. Mark Sloan" and "Lieutenant Detective Steve Sloan"
Back in the 70's "Diagnosis Murder", the two detectives "Dr. Mark Sloan" (Dick Van Dyke) and "Lieutenant Detective Steve Sloan" (Barry Van Dyke) play the stars of the show. "Dr. Sloan" was the medical specialist for the local police, always taking a look at the cases from his own perspective and more than often solving them.
