The script's the star of this sprawling six-part series from Frederic Raphael: probing, caustic and matchlessly witty, particularly in the two most successful episodes, the Brideshead-esque 'An Early Life' and the frankly outlandish 'A Past Life', which features Eric Porter as a fascist sympathiser. The acting is variable (Tom Conti's bravura central performance is the obvious standout), the worldview sometimes unsavoury and the penultimate episode has passages that really drag, but it's a work touched with a rare brilliance and the dialogue is simply spectacular. I picked it up after hearing Nigel Havers (who has a small but memorable role) say it was the best script he'd ever read.
