Agatha Christie. A mere mention of the name is enough to draw images of mystery, deception, distrust, and puzzles. To be able to construct a mystery in such a way as Christie is perhaps the dream of many a writer now, for not many could piece together a puzzle so intricate and clever that it keeps you guessing until the dying moments of the story itself. Her classic tale ‘The Mousetrap’ is the longest running play in West End history, but that, of course, isn’t her only hit.
