Against the Unknown
A GUMSHOE-based investigative roleplaying game of private detectives, cops, supernatural investigators and academics exploring unsolved murders and cases of mysterious phenomena.
The rules define what your character can accomplish in an investigative scenario. The rules don't care if your Accounting ability is one part native mental acuity to two parts training or vice versa, although you can mention them when describing your character to others. All that matters is how you solve cases, and overcome other obstacles arising from them.
