Rivulets trickled down her back, merging with the sweat seeping from her pores. Even with the windows open, and a fan oscillating as languidly as a spoon through soup, the temperature on the second floor of her house was hotter than the ambient air outside. She swiped the now-tepid cloth down her throat and paused at her collarbone. The washcloth soaked the thin ribbed fabric over her breasts while she considered the sheer curtains hanging lank beside the open window. Such an unremarkable thing, an open window, a simple pleasure people generally took for granted. Drew Norwood, her Navy SEAL boyfriend, had extensive experience managing risks of all shapes, sizes and situations. Given her borderline neighborhood, he’d weighed simple pleasures against physical safety and insisted on windows and doors locked tight at night. However, Drew had disappeared almost a month ago, as usual with no warning. Three times in the six months they’d been dating he’d simply vanished into thin air, reappearing weeks later sunburned, thinner and exhausted.
