I've just finished reading two books by Jeffrey Toobin that both take place largely in Los Angeles. One, American Heiress, is about the adventures of Patty Hearst. The other, The Run of His Life: The People v. O. J. Simpson, is about, well, you know what it's about. My connection with the Southern California city has been somewhat a charmed one. I've either visited on expense-account business trips. Or I've spent the night at the home of a friend, a movie star. Recently, a good friend has moved there from Boston, so maybe I'll be heading back for a visit.
