I remember watching this as a 14-year-old when it was originally televised. It really is a blast from the past. Great acting, good story lines - no computer graphics here. And the old London taxi? Fabulous! What you see is what you get. It's fun to see now well-established actors in small roles. Sadly, Sir Anthony Quayle is no longer with us, and Anneke Wills retired from acting long ago. Surprisingly, so few people seem to remember the show. It is every bit as good as its contemporaries - The Avengers, The Professionals etc. A shame only one series was made. It stands the test of time and will surely jog the memory for people of a certain age. Buy it and enjoy! 60s TV at its best.
