As there has been no official release of this programme after 30 years, and with no prospect of it happening because of some dispute, and my age, I decided to get an unofficial version. I put a phrase something like 'rare TV' or whatever it was into a search engine and was able to get a reasonable version with no problems. Obviously the quality cannot be anywhere near that of an official release but it is OK for me, but then I am not into Blue-Ray, HD, etc. So was it worth the money? Yes, for me, because I like ITV adventure series, even though I would say that the production/script writing/etc was not up to the standard of The Saint, The Avengers, etc. I also benefited from stopping fretting about whether I would ever get to see it. I don't agree with some other comments that I have seen. Rosalyn Landor was OK for me. Also, I enjoyed the second and third series just as much as the first. One qualification there, however. There is a significant change from the first series to the rest. The private eye aspect goes, and it is almost all security stories. The problem that I have with that is that they tend to be more unpleasant than private eye stories. However, a minor point.
