The Asylum and Other Tales
a collection of seven scenarios concerning situations that come up a lot in Call of Cthulhu games: an ocean voyage¸ a trip to a mental institution¸ an auction¸ reports of paranormal activity¸ and a few other things which have a more nebulous connection to the book's theme. Note also that all of these scenarios¸ as well as some others¸ were reprinted in 'Cthulhu Casebook¸' which is out of print.
