A few days of Columbo and mix it up with others from the NBC mystery movie show lineup.
Sort of what A&E used to do.
I remember those days. Columbo, McCloud, Rockford Files, Ellery Queen (with Jim Hutton and David Wayne), McMillan and Wife, Lou Grant, City of Angels (1976 series with Wayne Rogers), and Delvecchio (the Judd Hirsch one that I would have liked to have gotten into more and would not mind your’s or anyone’s opinion).
It would also be neat to bring M Squad, Dragnet, The Untouchables, Thin Man (with Peter Lawford), and other ‘50s cop/detective shows that have not been shown that much over the years.
