When does The New Perry Mason return?

The New Perry Mason is a CBS TV series that ran from 1973 to 1974. It was a revival of the 1957 Perry Mason television series about Erle Stanley Gardner's brilliant defense attorney. All of the major characters of the original series appeared in the revival, along with Gertie, a receptionist seldom seen in the original. The revival was cancelled at midseason after failing to overtake its two hit rivals, NBC's The Wonderful World of Disney and ABC's The F.B.I.
