Diagnosis: Murder

Diagnosis: Murder is a mystery/medical/crime drama television series starring Dick Van Dyke as Dr. Mark Sloan, a medical doctor who solves crimes with the help of his son, a homicide detective played by his real-life son Barry Van Dyke. The series began as a spin-off of Jake and the Fatman (Dr. Mark Sloan made his first appearance in episode 4.19 "It Never Entered My Mind"), became a series of three TV movies, and then a weekly television series that debuted on CBS on October 29, 1993. The series struggled at first and was almost canceled at the end of the second season, it returned as a midseason replacement in the third season, and was regularly renewed thereafter. 178 episodes were made and aired in the show's eight seasons on the CBS network in the United States and two more TV movies aired after the series' cancellation on May 11, 2001. Since 1997, the show aired in reruns on ABC Family (formerly The Family Channel) and on the Hallmark Channel. in America, weekdays on the Hallmark Channel (UK), Alibi and BBC One in the United Kingdom and weekdays on Foxtel's TV1 channel in Australia. The show was produced by The Fred Silverman Company and Dean Hargrove Productions in association with Viacom Productions and Paramount Network Television (1995 episodes only) and is currently distributed by CBS Television Distribution.

In the Jake and the Fatman episode, Dr. Mark Sloan was a widower with no sons and Ally Walker played Dr. Amanda Bentley, a role that went to Cynthia Gibb in the TV movies and, finally, Victoria Rowell in the TV series. Stephen Caffrey played Dr. Jack Stewart in the movies, a role that went to Scott Baio in the weekly series.

The first three TV movies were shot in Vancouver, British Columbia. The first few episodes of the series were shot (and set) in Denver, Colorado, before quickly (and without explanation) shifting to Los Angeles for the remainder of the show's run.
