She heard a loud banging at the back door, so ferocious and unexpected that she jumped. She returned to the kitchen, where she saw Mr. Ishiguro’s face pressed against the glass. She opened the door, awaiting an explanation. He was angry and his agitated English was gibberish to her. The more she shrugged and shook her head, the more infuriated he became. Finally he turned abruptly and motioned for her to follow. He set off down the path, walking so rapidly she had to trot to keep up with him. Turning a corner, she slipped and caught herself, but not before her foot skidded off the stepping stone and onto the countless parallel rake marks meant to quiet the mind. Nora laughed. She couldn’t help herself. It always struck her as funny when other people fell. There was something comical about the complete loss of dignity, the flailing attempt to recover one’s balance. Even animals suffered embarrassment when they slipped and fell. She’d seen cats and dogs stumble and then shoot a quick look around to see if anyone had noticed.

At the sound of her laughter, Mr. Ishiguro turned and lashed out at her, yelling and shaking a fist. She babbled an apology, trying to compose herself, but a part of her had disconnected again. Why should she put up with the incoherent ravings of a yard man, for god’s sake, whose only purpose was to maintain a stone gray landscape created to prevent the house from burning down. Laughter bubbled up once more and she faked a coughing fit to cover the sound. If he caught her laughing again, there was no telling what he would do.

Another ten feet along the path, Mr. Ishiguro stopped and pointed repeatedly, expressing his disapproval in a rapid series of what she took to be insults. On the ground there was a pile of animal feces. The compact deposit of excrement sat in the center of a composition of white pebbles he’d labored over the week before. It was coyote scat. She’d seen the pair for the past month, a big gray-and-yellow male with a smaller rust-colored female, picking their way along one of the trails, their bushy tails held down. They’d apparently established a den close by and regarded the neighborhood as one big cafeteria. The two coyotes were thin and wraithlike, and their posture suggested stealth and shame, though Nora thought they must be deeply satisfied with life. Coyotes weren’t fussy about what they ate. Squirrels, rabbits, carrion, insects, even fruit in a pinch. A number of neighborhood cats had vanished, most noticeably on nights when the howling and yipping of the pair suggested a hunting free-for-all. The male wasn’t above scaling the wall to drink from her reflecting pool, and Nora wished him well. Channing, on the other hand, had twice gone out with his handgun, shouting and waving his arms, threatening to shoot. The coyote, unimpressed, had loped across the patio, leaped the wall, and disappeared into the scrub. The female had been conspicuously absent for the past few weeks, and Nora suspected she had a litter of pups tucked away. Having watched Mr. Ishiguro obsess over the placement of every stone in the garden, she could see how a coyote taking an unceremonious dump on his path was the equivalent of an interspecies declaration of war.

“Get a hose and squirt it down,” she said when he paused for breath.

He couldn’t have understood a word of this, but something in her irrepressibly jocular tone set him off again, and she was treated to yet another tirade. She held up a hand. “Would you stop?”

Mr. Ishiguro wasn’t finished with his complaint, but before he launched in again, she cut him off. “HEY, you fuck! I wasn’t the one who crapped on your fucking rocks so get out of my face.”

To her astonishment, he laughed, repeating the expletive several times as though committing it to memory. “You fok, you fok . . .”

“Oh, forget it,” she said. She turned on her heel, went back into the house, and banged the door shut behind her. Within minutes her head was pounding. She hadn’t driven ninety miles to take abuse. She climbed the stairs and went into her bathroom. She opened the medicine cabinet in search of Advil, which was sitting on the bottom shelf. She shook two into her palm and swallowed them with water. She studied herself in the mirror, marveling that recent revelations hadn’t altered her outward appearance. She looked the same as she always did. Her gaze shifted to the wall behind her and she turned with a fleeting sense of disbelief. Thelma had left a monstrous brassiere hanging over the towel warmer just outside Nora’s shower door. Good god, was Thelma staying here? She’d apparently hand-laundered the garment, which featured stiff, oversize lace cones sufficiently reinforced and buttressed to support the weight of two torpedoes. Nora was appalled at the casual appropriation of her space, though why she bothered to react at all was a question worth examining.
