Alex Tilney, author of The Expectations, joins his longtime friend and occasional racquet-sports opponent Carl Bialik to talk about how squash figures in both his novel and an exclusive slice of American society, why substituting tennis for squash would have made for a very different tale, and what tennis and squash can learn from each other about keeping spectators entertained.
