My partner, Alex, had gone to "run an errand." He'd been gone a suspiciously long time. I heard his voice, through the thin wall of a nearby rental. He sounded panicked and stressed.

My teeth suddenly felt cold, my skin prickled with goosebumps. The sand beneath my feet felt less comfortable. Something was very wrong.
