Case solving RPG options
I'm looking for something that involves solving a series of smaller mysteries/cases/hunts etc. Basically 2-3 session chunks of content that can be played out and then maybe another month or two passes and we jump in for another. Even better if they make for an interconnected narrative.
My preference would be something smaller and on the lighter side in terms of complexity, i'm shying away from delta green, call of cthulhu.
Early research has me looking at... Triangle agency Bringdlewood Bay/The Between
What other things should i be checking out? Cheers
