This scenario is set in Massachusetts in late September of 1926, during the days of Prohibition. It is presented as aseries of clues, locations, threats, and non-player characters (NPCs). There is no right or wrong way for a groupof players to approach the scenario, and it is possible that your group will tackle things in a different order thanexpected or bypass some of the locations entirely. This is perfectly fine. Simply present the locations as the investigators encounter them and play the NPCs according to their motivations. Consequently, there are a number of ways in which the game can end; these are outlined in the section entitled Wrapping it all up.Advice for the Keeper is included within the text (Keeper’s Notes). Much of this advice is designed for new or inexperienced Keepers, and so may be obvious to the more experienced; however, some advice may also be helpful in learning how to apply aspects of the Call of Cthulhu rules.Keepers are advised to read the scenario through before starting play, as this will also help to decide how theinvestigators are introduced to the story. Two possible options are presented: as bootleggers, or a team from theMiskatonic University.
