A couple of years ago the judges for the Bollinger Everyman Wodehouse prize for comic fiction decided that none of the sixty two books submitted was funny enough to win, so they withheld the award. One of them, the publisher David Campbell, explained: ‘Despite the submitted books producing many a wry smile amongst the panel during the judging process, we did not feel than any of the books we read this year incited the level of unanimous laughter we have come to expect.’ Humour is notoriously subjective, but I am confident that if the prize had existed sixty-seven years ago, Gwyn Thomas’s A Frost on My Frolic would have been a strong contender.
