Nathaniel Rich's new novel King Zeno (Farrar, Straus and Giroux) is set in New Orleans a century ago, when a series of ax murders had the city on edge. The story follows a detective, a cornetist named Isadore Zeno and the widow of a crime boss — as jazz spread and the city changed following the end of World War I and the official closing of the prostitution district of Storyville. Rich is the author of Odds Against Tomorrow and The Mayor's Tongue. At 6 p.m. Tuesday, the book's official release date, novelist Katy Simpson Smith (Free Men, The Story of Land and Sea) interviews Rich, and he signs copies of the book at Garden District Book Shop. 2727 Prytania St., (504) 895-2266; www.gardendistrictbookshop.com.
