Mounting-dread voice: Kendall

Mounting-dread voice, escalating, tense, and horror-struck

Prompt: A voice built on mounting dread—starting calm and rational, tightening word by word as a slow horror dawns, the realization creeping in. The tone begins level and drifts higher and thinner, pauses growing, breath catching as understanding arrives. There's a hair-raising, something-is-very-wrong escalation to it. It sounds like a voice slowly piecing together a terrible truth, and wishing, too late, that it hadn't.

Script: It's probably nothing, the house just makes sounds at night, old houses do that, it's fine, it's just the pipes, or the wind. Except there's no wind tonight and that, that wasn't the pipes, that was footsteps, upstairs. But I'm the only one home. I'm the only one... wait.
