Sherlock Holmes stories have always been popular since they were written by Sir Arthur Conan Doyle and published from 1887 but have had a resurgence, and were likely to have been introduced to a whole new generation, thanks to the award-winning BBC Cymru Wales series Sherlock that began in 2010.
Starring Benedict Cumberbatch as Sherlock and Martin Freeman as Dr John H. Watson and filmed predominantly in Wales, the programme ran for four series, plus a Christmas special, and aired around the world and is still very popular.
The much-loved and enduring stories were the creation of Sir Arthur, a prolific author who also wrote science-fiction stories, plays, historical novels and poetry. He died in 1930 and spent much of his latter years at a stunning rural retreat that is now for sale.
