She was never more of a professional, never more defensibly excused from her caretaking duties in Denver, than when she was locked in a hotel room with her green-tea bags, her anonymized Wi-Fi connection, her two colors of ballpoint, her Ambien stash. But from the moment she arrived in Amarillo, on a commuter jet from Denver, something felt different. It was as if she didn’t even want to be in Amarillo. The normally pleasurable economies of her competence, the preferred-customer getaway from the rental-car lot, the optimal route she took to the small house of Janelle Flayner, the swiftness with which she secured Flayner’s trust and got her talking, weren’t pleasurable. Late in the afternoon, she stopped at a Toot’n Totum convenience mart and bought a chef salad in a polyethylene box. In her hotel room, which a recent occupant had smoked in, she uncapped the cup of salad dressing and felt nailed by the product’s targeting of her demographic: the solitary 50+ female looking for something sensible to eat.
