She hums under her breath, eyes still focused on the blur of the roadside, drifting farther away from him. She couldn't stop it, because she'd only been looking for outside forces. She'd completely missed the most common cause of domestic murder, the inside force. Her father's careful concealed psychosis. She'd looked with child's eyes instead of using all her training and all her resources.

She'd failed.

If that was the only way she'd ever get home, then not only had she failed her parents, but she'd failed Molly as well.

She tucked her hands under her thighs, shoulders hunched up under her ears, chewing on her lip. She was beyond tears at this point. She was numb.
