Carnacki, the Ghost Finder

Don't be fooled by the title, most of the cases in this book turn out to have very human causes. This book from 1913 feels very Sherlockish: in each short story the great gentleman detective Carnacki invites our writer to his home to tell him about his latest investigation while puffing on his pipe.

Good stories well told, I'm so glad I stumbled across these. They are free to download on Project Gutenberg and elsewhere.
