In the stories in this collection compiled by Nick Rennison, horrors from beyond the grave and other dimensions visit the everyday world and demand to be investigated. The Sherlocks of the supernatural - from William Hope Hodgson's 'Thomas Carnacki, the Ghost Finder', to Alice and Claude Askew's 'Aylmer Vance' - are those courageous souls who risk their lives and their sanity to pursue the truth about ghosts, ghouls and things that go bump in the night.
