The Trail of Cthulhu Keeper's Screen gives you the most important tables, rules, and references for GUMSHOE. Combat, contests, tests, and the mind-shattering Stability tables are there at your fingertips, letting you spend more time GMing and less fumbling through rulebooks. And, on the players' side, Jérôme Huguenin's breathtaking artwork will add to your game's eldritch atmosphere.
Included with the screen is the Keeper's Resource Book -- not the last scribbled words of a madman, but a carefully researched collection of clues, special benefits, game-relevant historical data, NPCs and occupational information for use in play. Each ability includes1930s equipment and practices, focused on their use in adventures to bring your game to life. Sprinkle the sample clues we provide, and offer the listed special benefits to your players.
Occupations have detailed backgrounds you can use to flesh out character backgrounds and NPC contacts; discover their techniques, weaknesses and foibles. Need a mad scientist or a fence? Select from a range of NPCs: Some are throwaway thugs and cultists; others, detailed contacts with forbidden knowledge -- partrician academics, antiquarian book dealers, professional rivals. Each NPC has three quirks or mannerisms so you can roleplay them consistently, and hooks they can provide to your players.
Finally there is a handy Sanity and Stability summary, with page references to the main book.
