Sir Arthur Conan Doyle’s greatest creation tackles a stream of mysteries in the Sherlock Holmes – Die geheimen Fälle des Meisterdetektivs audio-play series. Since the first of 50-plus episodes was aired in 2011, this German production—whose subtitle translates as “The Secret Cases of the Master Detective”—has been crafted by audio-play label Titania Medien for adults and young listeners alike. Along with some old cases to be cracked by the sleuth, there are plenty of new conundrums written by author Marc Gruppe with much intrigue and humour along the way.
