In From the Cold
This collection provides eight pre-generated investigators for use with the Cold Warning scenario. Each has a connection to the adventure, while remaining suitable for any 1920s-era Call of Cthulhu game. Seven investigators are based on characters from Golden Goblin Press publications, and one is original to the supplement.
