The Baron is right on the money with his review of this taut espionage series which was unfortunately not too successful because people expected it to be an all-action show in the mould of The Professionals, but in fact, it has more in common with the 1973/1974 series of Special Branch. Barber & Duffy work for Saracen, a private security company who specialize in protecting politicians, scientists, members of foreign Royal families and other assorted VIPs, but they often find that their charges have secrets to hide so with the help of colleagues Alice (the excellent Ingrid Lacey) and ex-policeman Eric (John Bennett), they investigate the ones that they're guarding while trying to keep them alive.
This is a rather grim series because a fair number of important people guarded by Saracen actually die and even though some might find this implausible, it adds more drama and suspense. Chris Burgess is dependable as the reserved Barber, but he is outshone by Jimmy Clarke as Duffy, an ex-Delta Force commando with an eye for the ladies and a sense of humour, but not a man you'd want to mess with. He excels at the action scenes which usually involve him running, jumping, fighting and shooting when the need arises. He is a bit like an American Lewis Collins.
Such a pity a further series wasn't commissioned. If they attracted writers like Murray Smith and Roger Marshall, I'm sure this would have gone from strength to strength. Best episodes are Starcross, Next Year In Jerusalem, Into Africa and the harrowing Reaper. There are also three future soap stars to spot - Steve McFadden and Lucy Speed from EastEnders and Jimmi Harkishin from Corrie.
If you want more in the way of action, watch The Zero Option, the pilot episode which is an extra on the last disc. It opens with a tense SAS raid and features some spectacular aerial and car stunts near the end as well as a frantic gun battle.
