Despite the other negative reviews concerning this programme, it was one of my favourites that year. I well remember this as being a very gentle comedy/drama, and (again contrary to other comments) considered that the chemistry between the two principal leads worked excellently well. The subtle humour and banter between Rodgers and Hempel made it one of those "will they won't they" scenarios, very much akin to the Steed/Peel coupling in the 1960's Avengers. Certainly for 1974 it was a great tonic and wonderful relief from the grim reality of that year of the Heath Government. A great pity there were no more than the original six episodes. However six was probably the right number and I suspect that more would have meant less, so to speak. Nevertheless I would dearly enjoy seeing them all again, they have truly vanished without trace and there are, for example, no listings at all on ebay from amateur recordists. Indeed, even Wikipedia makes no mention of the series under Anton Rodgers - maybe he was also disappointed and wished to remove any connection with it? Nevertheless, Zodiac has one fan - me!
