Well hello!!.. Sherlock Holmes: The Definitive Collection by Arthur Conan Doyle, narrated by Stephen Fry. As a kid I used to listen to the hounds of the Baskerville's on repeat.. No idea why I don't like scary stories as an adult. The content is long I feel like I've been listening to Sherlock's adventures for months but every moment has been exciting as I try to figure out myself whats been going on. Stephen Fry's notes are amazing and you should check out his work Mythos. It's of course a classic set of tales that have stood the test of time. Highly recommend maybe as a book that you read one adventure at a time as a bed time story :^)
