Much as he did between The Da Vinci Code and The Lost Symbol, the American writer is already speculating about Harvard symbologist Robert Langdon’s next case. In Milan for the opening of the opera season, Brown said La Scala, the Italian city’s world-famous theatre—and a hotbed of emotion, smoldering passion and professional intrigue—would make a perfect setting for a murder scene. Looking up at La Scala’s six rows of gilded, tiered balconies, the author said, “Somebody clearly needs to fall. I definitely need to go up there.” He said he would give serious thought to incorporating the opera houses into his next thriller. “It is quite possible. I’m mesmerized by this,” Brown said during the visit on Monday night. “The architecture, the art, and of course you have an endless cast of characters that can be built on.” The multi-millionaire author has always drawn heavily on Italian culture and history for his best-selling books.
