When a waitress stopped by, Kendall ordered cauliflower tacos with no sauce; Lockwood asked for fish ones without tortillas. “It’s very embarrassing, because it became a podcast diet,” she said of her keto regimen, in a tone that suggested that embarrassment, for her, is more of a theoretical than a felt phenomenon. Lockwood, who is forty-three, has close-cropped hair, expressive hands, and the rapid-fire, matter-of-fact confidence of someone who speaks even faster than she thinks. The playwright Heidi Schreck, who helped to adapt Lockwood’s life story for television, told me, “The first thing that always comes to mind, when I think of Tricia, is that self-portrait of Hildegard von Bingen”—the twelfth-century German abbess and mystic, who, in a book devoted to her divine revelations, depicted herself with a writing tablet on her lap and flames shooting out of her habit. Lockwood’s lack of inhibition can lead to trouble. At a panel in New York hosted by the Women’s Prize earlier in the spring, she suddenly slid off her stool mid-gesticulation. She no longer allows herself to do karaoke.journey-inline-newsletterinline-newsletter
