When does Mannix return?

Mannix is an American detective television series that ran from 1967 to 1975. The title character, Joe Mannix, is a private investigator played by Mike Connors. Mannix was not generally known as a show that explored socially relevant topics. Several episodes had topical themes.
During the first season of the series, Joe Mannix works for a large Los Angeles detective agency called Intertect, which was the planned original title of the show. As opposed to the other employees, Mannix belonged to the classic American detective archetype, thus he usually ignores the computers' solutions, disobeys his boss's orders, and sets out to do things his own way. Mannix also has a working relationship with the Los Angeles Police Department as he exchanges information with his contacts.
