Ethan Caldwell had oiled the front-door locks himself the night before. No squeaks, no warnings. The house in upper Northwest D.C. lay in that deceptive hush that comes right before everything changes. He turned the brass knob with deliberate slowness, black leather glove creaking faintly, briefcase in the other hand—not for actual work, but for the performance.

Officially, he was thirty-five thousand feet above the Atlantic, en route to a fintech summit in Geneva. Officially, the Georgian townhouse stood empty of him, giving the new nanny free rein to reveal her true nature.

Ethan despised uncertainty. Since losing Claire two years earlier, his world had shrunk to color-coded calendars, NDAs, and enforced quiet. Four nannies dismissed in fourteen months: one for chronic lateness, one for scrolling TikTok during bottle time, one whose laugh grated against the walls still heavy with grief, one who simply failed the vibe check administered by Margaret, the longtime housekeeper.
