Arthur Morrison wrote mysteries. His most famous detective -- possibly, his only detective -- is Martin Hewitt. Morrison is also remembered for his realistic fiction set in the slums of London's East End.

However Morrison's very first book is a collection of ghost stories, titled The Shadows Around Us: Authentic Tales of the Supernatural (1891). Various websites refer to this as a collection of short stories. But no. It retells a number of ghost stories -- tales reputed to be true.
