Publisher's blurb Advanced Class - Gumshoe details a D20 Modern Advanced Class for your pulp-genre campaigns. The Gumshoe... the P.I... the Detective: the pulp archetypes of the tough-as-nails, rough-around-the-edges, hard-boiled investigator. A file cabinet filled with cases, a beat-up desk, a name on the door and a reputation for getting his man. Many times, this is all a Gumshoe has to call his own, but while his life is often unglamorous, it is hardly ever boring.
