Emma first met Riley while the girl was hiding in a closet. Instead of coaxing too hard, she sat on the floor outside the door and told a story about a cat named Milo who used to fear the dark until he learned he was no longer alone. Silence lingered. Then the closet door cracked open.

Riley asked, “Did the cat stop being afraid?” Emma smiled and said yes, because he realized he did not have to face the night by himself. Riley came out.

That afternoon Emma read to her in the sitting room, and when the book closed, Riley asked softly, “Will you stay a long time?” Emma answered, “As long as you want me to.” Vanessa passed by with a glacial stare and said nothing, which was somehow worse.

That first night Riley woke in terror, convinced her “mom” had come into the room to tell her she still had to study. Emma gathered her into her arms, soothed her, and sang a lullaby so gently that even the wind outside seemed to quiet down.

Michael stood unseen in the doorway, watching his daughter rest against someone with more peace than he had given her in months. The next morning Vanessa found Emma in the kitchen making warm milk and snapped that no one had asked her to step beyond her limits.

Michael intervened and, for the first time, told Vanessa plainly to stop taking her frustrations out on the nanny. Vanessa smiled with a razor-thin mouth and said perhaps he had finally found someone who could take better care of the child than she could.

Later, while tidying Riley’s room, Emma found a stack of drawings hidden under the pillow. In one, a brown-haired woman embraced Riley—that was Emma. In another, a woman in a red dress held a ruler—that was Vanessa. Riley stood between them with huge frightened eyes.

Beneath the image were the words, “I’m scared.” Emma closed the notebook slowly and left it exactly where she had found it, but her heart would not settle after that. At dinner Michael asked Riley about school and piano, and Riley told him she liked practicing more now because Emma taught “more softly.” Michael laughed—really laughed—for the first time in months. Across the table Vanessa gripped her wineglass so tightly her knuckles went white.
