Mannix The Search for Darrell Andrews (1967–1975) Online
Wes Tully, a private detective who is a friend of Joe Mannix, is killed by two men who carefully stage his death to look like an accidental drowning. But Tully had confided in Mannix that he might be killed because of a case he was working on, and that his death would be made to look like an accident. Believing that his friend was murdered, Mannix retrieves some important evidence from the case Tully was working on -- but that only prompts the men who killed Tully to threaten Peggy and Toby in order to get that evidence back.

The set used as the entryway for the home of Martin Kimbrough (Harry Townes) is the same used as that used as the entryway of Dr. Wallenberg's home in the previous episode, "Fly, Little One" (where Dana threatens to "fly away" from the second story landing near the beginning of the episode).
