Quoting Dicebreaker:
"[Arkham] will be followed by two adventure collections for Call of Cthulhu. The first will be Call of Cthulhu: The Order of the Stone, a new three-part campaign set during the 1920s. The Order of the Stone will be released this April.
Following that, an currently untitled Call of Cthulhu scenario collection will make its way to the table in May. The previously unannounced anthology is billed by publisher Chaosium as a follow-up to its 2020 book Gateways to Terror, which featured three standalone adventures and four pre-made characters designed to showcase the game’s mix of horror, investigation and mystery in sessions that could be wrapped up in just an hour or so.
The new scenario collection is similarly designed to work as a next step from Call of Cthulhu’s Seventh Edition Starter Set, allowing new players to take on the scenarios without requiring the RPG’s full core rulebook [Keeper Rulebook]. Each adventure will last around one hour."
