In the autumn of 2018, Luna found herself on Foster Hill Road, a gravel lane that winds through the woods outside Millbrook, New York. She was there to document a series of strange reports from residents about a low, rhythmic tapping that seemed to come from inside the walls of an old farmhouse. The tapping had a pattern—three knocks, a pause, then three more—repeating all night, every night, for weeks. Luna spent a long weekend in the house, recording audio and trying to find a natural explanation. But the tapping wouldn't stop. And by the third night, it had started to answer her. A quiet, intimate story about a sound that should not have been there, and the loneliness of being the only one who hears it. No answers are given. Only the memory of that rhythm, and the feeling that something was listening back.
