This season, CBS cut the “Mystery” from 48 Hours Mystery. Under either title, it’d be hard to imagine Saturday nights without this venerable TV series. How low would the ratings have to go for it to be cancelled? Last season, the numbers declined. Will they keep going? Stay tuned.

48 Hours typically airs on Saturday nights on CBS. Correspondents include Richard Schlesinger, Erin Moriarty, Susan Spencer, Peter Van Sant, Troy Roberts, and Maureen Maher.
