“Have You Seen the Yellow Sign?”
Insanity quickly follows dark dreams in this tale of a mystery writer who succumbs to madness. Agatha Christie as a cultist is a nice touch.
“The Eye of Horus”
A very short tale of a nameless pharaoh whose body is stolen by a Yith, his dealings on the far side of space, and what he did when he returned home.
“Great Cthulhu”
When a museum curator is bequeathed the estate of her tinfoil-hat-wearing friend who's finally cracked, little does she realize that she won't have a long time to enjoy that apartment she's just inherited. Because those crazy cultists in the university that her friend was investigating? Yeah, it was the Miskatonic and they just woke up Cthulhu.
"The Blind Idiot Godhead"
My favorite so far, about teenaged Evelyn and her recently deceased grandpa whom everyone seems to be forgetting, and Azathoth, whose dream is our reality.
"Nyarlathotop: The Man With No Face"
An odd tale of sacrifice from the perspective of the victim.
