I came across this after appearing in the 2007 series of Mastermind myself. Of course, Magnus Magnusson stopped presenting the show after its first phenomenally successful 25 year run came to an end in 1997, and indeed died earlier in 2007. A great pity. I'd have loved to have met him, and feel this even more so after reading his book.
This is a very good read. Possibly it helps to have an interest in quizzing, or in the way that television works behind the scenes, but its not essential. Magnus was a good and engaging writer, which is no less than you'd expect from a man with all of his journalistic experience. For 25 years 'Mastermind' was something of a national institution, and Magnus' great pride in and enjoyment of his involvement with the show shines through, as does his admiration for 25 years' worth of contenders, both the winners who are generously profiled, and those who did not do quite so well, all of whom are remembered with affection. He explains how the show came to be, and how a stroke of fortune turned the show from a late night filler for intellectual insomniacs, to prime time entertainment captivating millions of viewers every week. He describes some of the highlights from the show's history, for example the great joy that accompanied the victory of London cabbie Fred Housego in the 1980 series, and some of the lowlights as well. What emerges is a warm , affectionate and indeed infectious portrait of a true classic of British television. A good read.
