“Two hours and fifty-five minutes. That's how long it takes before I find something that makes me sit up in bed. It’s dark, late evening. Evie asleep in the nursery. We must have been downstairs. At one point there’s movement. Evie’s little nightlight wasn’t on, but if you squint, you can see a shadow against the far wall. Chloe. She's crouched in the corner of the room. Then Evie starts to cry and literally one second later the shadow slips out of the room.”
