Has it really been 100 years since Lady Brett Ashley breezed into a Paris night club to tromp all over Jake Barnes’s heart? Since the Lost Generation found the bullfights in Pamplona? Yes, Jay McInerney, a collector of Hemingway first editions, reminds us. On Oct. 22, a century to the day that The Sun Also Rises was published, he and fellow novelist Thomas Beller will preside over a birthday celebration of the genre-detonating novel, with readings by actors Sarah Pidgeon, Maya Hawke, Titus Welliver, Dominic Sessa, Richard Schiff, Lucas Hedges, Joy Sunday, Penn Badgley, and Will Harrison, and several Hemingway family members in attendance. “Built with curves like the hull of a racing yacht,” Lady Brett has staked her claim on all three willowy actresses. —Celia McGee
