About a third of the way through “Farewell, Amethystine,” the latest novel in the author Walter Mosley’s series about a private investigator named Ezekiel (Easy) Rawlins, Easy sets out for a late-night meeting with a gun and a hunch.

The book is on a narrative precipice in which our gumshoe has knocked on enough doors and been told enough lies that both he and the reader understand that the simple missing-person case presented in Chapter 2 is about to become violent.

But before it goes down, Easy pauses the action to make a weird declaration: He doesn’t need this job. He makes more than enough money renting real estate.

Easy is a Black World War II veteran who fled the Jim Crow South for a better life in Los Angeles. In “Devil in a Blue Dress,” the 1990 classic that started both the series and Mosley’s career, Easy takes his first case so he can pay his mortgage and uses a windfall to add a rental property. The ups and downs of real estate continue as a recurring theme and story engine, especially in the early books, where the remedy for some tax lien or underwater mortgage is often to solve whatever mystery is driving the plot.

Now, two decades of buying and holding later, Easy is flush. As he explains in “Farewell, Amethystine,” his 12 buildings have a total of 101 rental units that a friend manages for a 0.8 percent fee. Subtract that commission along with mortgage payments and general upkeep, and his take-home is $26,000 a year in 1970 (the year the novel takes place), which, adjusted for inflation, would be about $217,000 today.

“I wasn’t rich,” Easy says. “But I sure didn’t need to be going out among the hammerhands and scalawags in the middle of the night.”
