This is the hint.
This book of Times Jumbo crosswords gathers together all sixty of the puzzles published in The Times from August 2005 to August 2006.
In preparing them for publication here I’ve reviewed the clues and taken the opportunity to alter a few that no longer seem quite as clear as I fondly imagined when I first submitted them for publication.
Those who’ve solved puzzles in the earlier volumes in this series will know what to expect, for the intended level of challenge remains about the same. A smattering of general knowledge weaves its way among the straight definitions but is never, I hope, particularly obscure. This aspect of the puzzles sometimes causes me a lot of thought as to what is acceptable general knowledge for this purpose. Some parts of more recent popular culture are strongly generation dependent, so one person’s much-loved film star may be entirely unknown to or only hazily recognised by a later generation brought up on films made since the star retired, while references to, say, pop music will sometimes date terribly within five years. I try to steer a middle path which includes all aspects of culture, sports and sciences in moderation but in the end my decision on whether to include a particular answer depends on my own feeling as to how recently I’ve seen references in the press or online and, mindful of the delay before anthologies such as this appear, how quickly it may date.
As in The Times Jumbo Crossword Book 3, these puzzles are mainly of my own devising, but six that were published as extra puzzles on Bank Holidays and over the Christmas period are by Richard Browne, Dave Crossland and Don Manley, two from each of them. I am also grateful to Dave Crossland for sharing the task of proofreading and suggesting a few improvements along the way.
