For those that haven't seen it, I recommend The Sandbaggers, a 20 episode TV series that originally ran in the UK on ITV from 1978-1980. Roy Marsden does a fine job starring as the head of MI6. Some of the sets for interior scenes were laughably low budget, but the acting and writing were quite good. For a dash of added intrigue, the writer and his girlfriend disappeared under mysterious circumstances and were presumed dead during the production of the third and final season.
The Wikipedia entry is here: https://en.wikipedia.org/wiki/The_San.... Netflix had the series a while back, but doesn't seem to at the moment. I would guess that it will rotate back into their offerings over time. The entire series appears to be available on YouTube here: https://www.youtube.com/channel/UCJ-O....
