The Good Daughter: The gripping new bestselling thriller from a No. 1 author. Karin Slaughter

feels too sad in here,” her sister had said, slowly backing out of the upstairs bathroom.

      The tub was not the only thing that Charlotte found unsettling. The spooky, damp basement. The creepy, bat-filled attic. The creaky closet doors. The bedroom where the bachelor farmer had died.

      There was a photo of the bachelor farmer in the bottom drawer of the chiffarobe. They had found it this morning on the pretense of cleaning. Neither dared to touch it. They had stared down at the lonesome, round face of the bachelor farmer and felt overwhelmed by something sinister, though the photo was just a typical depression-era farm scene with a tractor and a mule. Samantha felt haunted by the sight of the farmer’s yellow teeth, though how something could look yellow in a black-and-white photo was a mystery.

      “Sam?” Gamma stood in the bathroom doorway, looking at their reflections in the mirror.

      No one had ever mistaken them for sisters, but they were clearly mother and child. They shared the same strong jawline and high cheekbones, the same arch to their eyebrows that most people took for aloofness. Gamma wasn’t beautiful, but she was striking, with dark, almost black hair and light blue eyes that sparkled with delight when she found something particularly funny or ridiculous. Samantha was old enough to remember a time when her mother took life a lot less seriously.

      Gamma said, “You’re wasting water.”

      Samantha tapped the faucet closed with the small hammer and dropped it back into the sink. She heard a car pulling up the driveway. The sheriff’s man, which was surprising because Rusty rarely followed through on his promises.

      Gamma stood behind her. “Are you still sad about Peter?”

      The boy whose leather jacket had burned in the fire. The boy who had written Samantha a love letter, but would no longer look her in the eye when they passed each other in the school hallway.

      Gamma said, “You’re pretty. Do you know that?”

      Samantha saw her cheeks blush in the mirror.

      “Prettier than I ever was.” Gamma stroked Samantha’s hair back with her fingers. “I wish that my mother had lived long enough to meet you.”

      Samantha rarely heard about her grandparents. From what she could gather, they had never forgiven Gamma for moving away to go to college. “What was Grandma like?”

      Gamma smiled, her mouth awkwardly navigating the expression. “Pretty like Charlie. Very clever. Relentlessly happy. Always bubbling up with something to do. The kind of person that people just liked.” She shook her head. With all of her degrees, Gamma still had not deciphered the science of likability. “She had streaks of gray in her hair before she turned thirty. She said it was because her brain worked so hard, but you know of course that all hair is originally white. It gets melanin through specialized cells called melanocytes that pump pigment into the hair follicles.”

      Samantha leaned back into her mother’s arms. She closed her eyes, enjoying the familiar melody of Gamma’s voice.

      “Stress and hormones can leech pigmentation, but her life at the time was fairly simple—mother, wife, Sunday school teacher—so we can assume that the gray was due to a genetic trait, which means that either you or Charlie, or both, could have the same thing happen.”

      Samantha opened her eyes. “Your hair isn’t gray.”

      “Because I go to the beauty parlor once a month.” Her laughter tapered off too quickly. “Promise me you’ll always take care of Charlie.”

      “Charlotte can take care of herself.”

      “I’m serious, Sam.”

      Samantha felt her heart tremble at Gamma’s insistent tone. “Why?”

      “Because you’re her big sister and that’s your job.” She gripped both of Samantha’s hands in her own. Her gaze was steady in the mirror. “We’ve had a rough patch, my girl. I won’t lie and say it’s going to get better. Charlie needs to know that she can depend on you. You have to put that baton firmly in her hand every time, no matter where she is. You find her. Don’t expect her to find you.”

      Samantha felt her throat clench. Gamma was talking about something else now, something more serious than a relay race. “Are you going away?”

      “Of course not.” Gamma scowled. “I’m only telling you that you need to be a useful person, Sam. I really thought you were past that silly, dramatic teenager stage.”

      “I’m not—”

      “Mama!” Charlotte yelled.

      Gamma turned Samantha around. She put her calloused hands on either side of her daughter’s face. “I’m not going anywhere, kiddo. You can’t get rid of me that easily.” She kissed her nose. “Give that faucet another whack before you come to supper.”

      “Mom!” Charlotte screamed.

      “Good Lord,” Gamma complained as she walked out of the bathroom. “Charlie Quinn, do not shriek at me like a street urchin.”

      Samantha picked up the little hammer. The slim wooden handle was perpetually wet, like a dense sponge. The round head was rusted the same red as the front yard. She tapped the faucet and waited to make sure no more water dripped out.

      Gamma called, “Samantha?”

      Samantha felt her brow furrow. She turned toward the open door. Her mother never called her by her full name. Even Charlotte had to suffer through being called Charlie. Gamma had told them that one day they would appreciate being able to pass. She’d gotten more papers published and funding approved by signing her name as Harry than she’d ever gotten by signing it as Harriet.

      “Samantha.” Gamma’s tone was cold, more like a warning. “Please ensure the faucet valve is closed and quickly make your way into the kitchen.”

      Samantha looked back at the mirror, as if her reflection could explain to her what was going on. This was not how her mother spoke to them. Not even when she was explaining the difference between a Marcel handle and the spring-loaded lever on her curling iron.

      Without thinking, Samantha reached into the sink and wrapped her hand around the small hammer. She held it behind her back as she walked up the long hall toward the kitchen.

      All of the lights were on. The sky had grown dark outside. She pictured her running shoes alongside Charlotte’s on the kitchen stoop, the plastic baton left somewhere in the yard. The kitchen table laid with paper plates. Plastic forks and knives.

      There was a cough, deep, maybe a man’s. Maybe Gamma’s, because she coughed that way lately, like the smoke from the fire had somehow made its way into her lungs.

      Another cough.

      The hair on the back of Samantha’s neck prickled to attention.

      The back door was at the opposite end of the hall, a halo of dim light encircling the frosted glass. Samantha glanced behind her as she continued up the hall. She could see the doorknob. She pictured herself turning it even as she walked farther away. Every step she took, she asked herself if she was being foolish, or if she should be concerned, or if this was a joke because her mother used to love to play jokes on them, like sticking plastic googly eyes on the milk jug in the fridge or writing “help me, I’m trapped inside a toilet paper factory!” on the inside of the toilet paper roll.

      There was only one phone in the house, the rotary dial in the kitchen.

      Her father’s pistol was in the kitchen drawer.

      The bullets were somewhere in a cardboard box.

      Charlotte would laugh at her if she saw the hammer. Samantha tucked it down the back of her running shorts. The metal was cold against the small of her back, the wet handle like a curling tongue. She lifted her shirt to cover the hammer as she walked into the kitchen.

      Samantha felt her body go rigid.
