I seem to recall Quincy was the last Mystery Movie series premiering in 1976, and it eventually it was shortened to 60 minutes after the NBC Mystery Movie ended in 1977. It continued to 1983. Meanwhile, Columbo was an occasional TV movie special during the 1977-78 season). Yes, I remember the Amy Prentiss character when Jessica Walter first played her in a 2-part episode of Ironside which spun her off into her own series. Jessica will never top her memorable psycho killer girlfriend role from Clint Eastwood's film "Play Misty for Me". Hec Ramsey ran a couple of years (1972-74) but I haven't been able to find it anywhere. Typing of Richard Boone, the only reason Have Gun, Will Travel reruns have aired on Hallmark Channel for several years (and also on DVD for a year now) is because it was a hit.
