"Welcome to the Bureau of Investigation, agents! Here are five very peculiar cases. I believe the individual who reported them has a fertile imagination. If these facts prove to be true, it will take you more than a strong stomach to solve them. Here are your badges... Good luck!"
Bureau of Investigation: Investigations in Arkham & Elsewhere is a complete and independent investigation game set in the Cthulhu Mythos. These cases transport you into the United States of America in the 1920s to tear the veil dissimulating unspeakable threats from Elsewhere. The game is based on the rules of Sherlock Holmes Consulting Detective, with a few added new investigative mechanics.
