The Seven Dials Mystery (TV Movie 1981)
Adapted from Agatha Christie's 1929 novel, this TV version takes us right back to the English aristocracy's last gasp when characters were called 'Pongo' and ''Bundle', and Bentley roadsters were thick on the ground. It wasn't all fun and games though because, when the cricket bats and hockey sticks had been stored away, there were serious things like mysterious societies, spies and secret formulae of national importance to be dealt with. That didn't mean that these too weren't a jolly jape or a spiffing wheeze to be enjoyed, so long as one was prepared to take the occasional risk that the unknown villain might be the least likely of one's fellow players. The important thing was that the bounder was eventually unearthed and true love blossomed in the knowledge that once again, England had been saved for those who knew best how to enjoy it. 7/10
