5.0 out of 5 stars A cracking spy yarn from the 1970s... 21 Sep 2009
Produced by Southern TV in 1975 this was first shown on the ITV netework in 1976 after the untimely death of John Gregson who plays the lead role of Kirby an insurance salesman or is he?
I originally watched this in weekly installments and could only just remember it after all these years. My memories of a fascinating story, great acting and brilliant music have been reconfirmed.
It is difficult to imagine such an excellent series being made today. N J Crisp wrote for TV from 1960 to 1999 and was involved with or conceived a wide variety of shows(Dr Finlays Casebook; Secret Army; A Family Affair, Dixon of Dock Green etc). This spy thriller with a top notch cast and giving John Gregson a final role of substance, also reaquaints us with Patrick Allen, what a voice, as Thane a senior civil servant and Prunella Ransome as the somewhat mysterious Laura.Also in the cast are Ralph Bates and Ruth Trouncer both well know faces.
All is not as it seems in this tale but it would be unfair to give the game away. This will be a must for fans of TV spy drama and it would be great to think that there is more in the ITV vaults like this to enjoy.

Southern Television presents Armchair Thriller Series ~ "DANGEROUS KNOWLEDGE" (19 May 1976) (UK) (148 min/Color) (Dolby digitally remastered) --- Would call this a thriller that has many twists and turns ---Deals with accusations that there is a traitor among us --- The plot keeps us in the dark, as we see the story through the eyes of our main character Kirby who is a mystery within himself, while maintaining a degree of suspense --- Highly recommend this six episode thriller that will satisfy many doubting fans of television made series.

5.0 out of 5 stars Another forgotten gem from Southern Television 26 Feb 2012
I really enjoyed Dangerous Knowledge from Southern Television. Some fine acting and effective direction give this a real `thriller edge', and the fine cast are deployed to good effect. For a mid-1970s TV drama, produced by a small regional ITV company, this has real quality; plenty of location filming, aerial sequences, car chases and a couple of shoot-outs. Some reviewers have criticised the plot, but I think it stands-up well (and all thrillers have plot holes to some extent), and it should be remembered that it was originally designed to be seen in weekly instalments, so watching it back-to-back is bound to shift our perspective on plausibility.

John Gregson and Patrick Allen were particularly good, but the whole cast was excellent - a special mention to Elisabeth Bergner, who gives a really believable performance as ex-spy Madame Lafois. A special mention too for the cracking theme music by Christopher Gunning - has to be up there with his best work, and it's a great shame that it's not better known; Gunning doesn't even mention it on his list of TV music credits on his website.

Oh, and finally, one reviewer states that Southern produced this as part of the ITV anthology strand Armchair Thriller, but this is not the case - it was a stand-alone drama from Southern Television that was networked.

Highly recommended.

I am somewhat ambivalent about this programme.

While I enjoyed revelling in the cosiness and charm of the less technically sophisticated mid 1970s, I found the conclusion of the story to be ultimately unsatisfying. If one were to analyse the story it would be shown to have glaring holes in the plot (but then again doesn't every James Bond story)?

Without giving too much away, if the villains of the piece knew where Kirby was staying why not just assassinate him and get it over and done with? And as an aside, just how much whisky can a man drink and still retain a clear head?

However, having said that, it is well worth watching if only for the divinely fragrant Prunella Ransome, who glowed throughout this production.

I should say that if this DVD were priced nearer £3.99 then I wouldn't have grumbled about it, but I'm sick and tired of being taken for a ride when buying what is essentially near out of copyright material, which has been dredged up from the TV archives and dumped onto DVD. Especially so when no new production costs have been incurred other than running the old footage though a digital scratch and dirt remover.
