Investigators are those who probe mysteries from a pragmatic, professional motivation. An investigator may be a Fortean writer, a
policeman, a private detective, a newspaper reporter, etc. To be an investigator, a character requires a minimum ES of 12 and a Stealth
of 12. He also rolls 3d6 to determine his permanent, intrinsic handto-hand fighting experience. This bonus is additional to the adds the
character receives for his Strength, Luck and Dexterity.

Consider this example of detective work:

SCHOLAR: Very well, so we discover that the Pickman family in their tomb is very deformed. I'm a doctor; do I see any Greater Significance?
GM: You do if you make a second level Saving Roll on your IQ.
SCHOLAR: (makes the roll successfully) What do I realize?
GM: (privately) You realize that the Pickman deformities resemble the ghouls you saw earlier today. The deformities begin with Reggie Pickman — his father Amos must have mated with a ghoul! For finding this much out, you get 100 KPs. But the knowledge is so shocking that you need a SR against Fear Reaction. First level will do.
INVESTIGATOR: (watching scholar make a successful SR) What is it, Doc?
SCHOLAR: Don't ask me! It's terrible! Unbelievable!
INVESTIGATOR: Tell me — I can take it on the chin!
(...)
SCHOLAR: No, it's better you don't know. I need your help if we're to get out of here alive. A nervous sort like you would surely go mad!

I was the staff illustrator for Sorcerer' Apprentice and also did maps for some of the adventures we published in "SA" (as we called it).
It also ran articles about different genres and ways to play {name of the game}, and one of the most memorable articles that fans spoke about for years were the two articles about playing the {name of the supplement} written by {authors}. These articles predated Chaosium's Call of Cthulhu rpg, and may have been the first time the Cthulhu mythos was used for an rpg rules variant ever put in a national magazine.
