The Unremarkable Heart by Karin Slaughter

dead in a pool of blood. She stumbles across two more intruders, and within minutes they too are shot dead. And when the Atlanta police force turns up, Faith has some difficult questions to answer. But she has some desperate questions of her own. What were the killers searching for? Ex-Atlanta police chief Evelyn Mitchell was once under investigation by Faith’s partner Will Trent. Is her mother directly involved this time, and where is she now?
    With Faith suspended from duty, Will, together with the help of Dr Sara Linton, must piece together the fragments of a brutal and complicated case – and catch a deeply troubled and vicious murderer with only one thing on his mind. To keep on killing until the truth is finally revealed.
CHAPTER ONE
    Faith Mitchell dumped the contents of her purse onto the passenger seat of her Mini, trying to find something to eat. Except for a furry piece of gum and a peanut of dubious origin, there was nothing remotely edible. She thought about the box of nutrition bars in her kitchen pantry, and her stomach made a noise that sounded like a rusty hinge groaning open.
    The computer seminar she’d attended this morning was supposed to last three hours, but that had stretched into four and a half thanks to the jackass in the front row who kept asking pointless questions. The Georgia Bureau of Investigation trained its agents more often than any other agency in the region. Statistics and data on criminal activities were constantly being drummed into their heads. They had to be up to date on all of the latest technology. They had to qualify at the range twice a year. They ran mock raids and active shooter simulations that were so intense that for weeks after, Faith couldn’t go to the bathroom in the middle of the night without checking shadows in doorways. Usually, she appreciated the agency’s thoroughness. Today, all she could think about was her four-month-old baby, and the promise Faith had made to her mother that she would be back no later than noon.
    The clock on the dash read ten after one o’clock when she started the car. Faith mumbled a curse as she pulled out of the parking lot in front of the Panthersville Road headquarters. She used Bluetooth to dial her mother’s number. The car speakers gave back a static-y silence. Faith hung up and dialed again. This time, she got a busy signal.
    Faith tapped her finger on the steering wheel as she listened to the bleating. Her mother had voicemail. Everybody had voicemail. Faith couldn’t remember the last time she’d heard a busy signal on the telephone. She had almost forgotten the sound. There was probably a crossed wire somewhere at the phone company. She hung up and tried the number a third time.
    Still busy.
    Faith steered with one hand as she checked her BlackBerry for an email from her mother. Before Evelyn Mitchell retired, she had been a cop for just shy of four decades. You could say a lot about the Atlanta force, but you couldn’t claim they were behind the times. Evelyn had carried a cell phone back when they were more like purses you strapped around your shoulder. She’d learned how to use email before her daughter had. She’d carried a BlackBerry for almost twelve years.
    But she hadn’t sent a message today.
    Faith checked her cell phone voicemail. She had a saved message from her dentist’s office about making an appointment to get her teeth cleaned, but there was nothing new. She tried her phone at home, thinking maybe her mother had gone there to pick up something for the baby. Faith’s house was just down the road from Evelyn’s. Maybe Emma had run out of diapers. Maybe she’d needed another bottle. Faith listened to the phone ring at her house, then heard her own voice answer, telling callers to leave a message.
    She ended the call. Without thinking, she glanced into the back seat. Emma’s empty car seat was there. She could see the pink liner sticking out over the top of the plastic.
    ‘Idiot,’ Faith whispered
