"They arrive in Tilly’s Cadillac, Uncle Andrew behind the wheel. He gets out, tall and lanky, and stretches his back before swinging the door shut. He’s a runner, a high-school math teacher and track coach on his second marriage. He has traveled the country running marathons, and in Boston and New York he places high in his age group; in smaller marathons he sometimes wins; he founded the Bloomfield Runners Club and for years has trained his students on weekends and summer break; he is a disappointment to his mother."
