"Harlem Shuffle" by Colson Whitehead.
It's the 1960s and this dude is trying to make a go of a furniture store on 125th Street. He's an honest businessman who wants to help people in the community get good products at a reasonable price, and provide for his wife and kids.
Of course, being an honest businessman in 1960s Harlem is a bit different from being an honest businessman in say Darrian, CT. So what if he's doing a little fencing; hanging out with stickup men; aiding corrupt police, and suchlike?
Great depictions of the neighborhood with lots of action.
