Lovecraft's "Under the Pyramids" is one of his most unusual works. It was a contract piece commissioned by "Weird Tales" magazine and was originally published as the real-life experience of magician Harry Houdini. The story lead to an ongoing relationship between Lovecraft and Houdini that only came to an end with the illusionist's death. Intriguingly, it was also a precursor to the intentional blurring of fiction and non-fiction that would become an important part of the Mythos and, eventually, conspiracy culture. There's a pretty straight line between Houdini's underground adventure and the "secret Hall of Records under the Sphinx" theories of late night radio.
Jason McKittrick is doing his part to further blur those lines with his latest project- Houdini's Secret. It's a fantastic collection of ephemera and physical props based on the story. The deluxe edition knocks it out of the park with a cool depiction of the Sphinx drawn directly from the text and a vintage shipping box.
