Based On The GUMSHOE System By Robin D. Laws
Trail of Cthulhu is a complete game of investigative horror set in the 1930s based on the work of H.P. Lovecraft. The game uses an adapted and enlarged version of GUMSHOE, a rules system that offers a laser-like focus on investigation, and encourages characters driven to explore and investigate, even at the expense of their own health and sanity.
