It's the 1920's, Dipper and Mabel are sent east to Chicago to go live with their Grunkle Stan. Despite it being the 1920's Dipper is still loves sci-fi and being a detective, Mabel is still wacky and enjoys crafts and being herself. Dipper gets himself in trouble with the gangs in Chicago and even the deceased gang lord of Chicago, Bill Cipher (he's a human in this au) I got most of my ideas for the story from Tybay on Deviantart, it's really good!! and since no one has written the story for it I'm going for it!!!
