'The Great Keinplatz Experiment' is a collection of short stories by the prolific 'Sherlock Holmes' author Sir Arthur Conan Doyle. Due to Doyle's fascination with the supernatural, several of the stories have a supernatural element. Stories in the collection include Egyptian archaeology thriller 'Lot No. 249' and the dark, atmospheric séance story in 'Playing with Fire'. Full of humour as well as mystery, this is a fascinating collection of stories from Doyle.-
