I had always loved the old willow that sprawled against my bedroom window. Its long, sweeping branches swayed gently in the breeze, filtering the morning light into a soft, green glow. The leaves whispered secrets I never quite caught, and the birds that nested within sang a lullaby each dawn. My room was on the second floor of a converted farmhouse, on the eastern side, overlooking the untamed meadow that bordered a shallow creek. The town was small, quiet, and I had moved here for the peace. I cherished the open window, the cool air, the scent of damp earth and leaf mold. I never closed it, not once, through the humid summers or the brisk autumn nights.
But this particular night, an unease crept over me as I lay in bed. The house seemed too still. The usual creaks and groans of settling wood were absent. The willow’s branches hung limp, not a single leaf stirred. A thought, unbidden, surfaced: ‘Close the window.’ It was irrational; the air was pleasant, the sky clear, but the thought persisted, a nagging whisper in my mind. I was already in my cocoon of blankets, exhausted from the day of unpacking. I dismissed it, yawned, and drifted toward sleep.
Just as consciousness began to dissolve into dream, a sound snapped me back. It was a clearing of a throat, but not human. It was deep, wet, and resonated as if from a cavernous chest. It came from outside, from the direction of the willow. My heart lurched. I lay rigid, straining to hear. There were no dogs in the vicinity; the nearest neighbor was a half-mile away, and they kept only cats. The sound was too large, too deliberate to be an animal like a deer or a fox. It sounded almost… patient. And then I realized: it was waiting.
I forced myself to sit up and peer out the window. The willow was a black silhouette against the star-filled sky. The branches, which had been limp, now swayed slightly, though the air was still. Or perhaps they had been moved by something within. I squinted, trying to discern a shape, a figure among the leaves. Nothing. But then, a low, guttural laugh, not loud, but full of amusement, rumbled from the tree. ‘Good evening,’ it said, in a voice that was raspy and old. ‘You must be the new one. They always keep the window open. They always listen, at first.’
My blood ran cold. I tried to speak, but my voice caught. The thing in the tree continued, its words carrying easily through the glass. ‘Don’t be frightened. I’ve been here longer than any of the houses. I only want to talk. It gets so lonely, watching you all come and go. And you have such a beautiful room. So open. So inviting.’ I grabbed the windowsill, meaning to slam it shut, but my hands trembled so violently I could barely grip it. As I fumbled, the creature spoke again, its tone dropping to a conspiratorial whisper. ‘I wouldn’t do that if I were you. Closed windows are a challenge. They make me have to knock.’ And then it laughed again, and the willow’s branches shook, though the night was calm.
I finally managed to close the window, the latch clicking into place with a finality that echoed in the room. My breath was ragged. I pulled the blinds shut, plunging the room into darkness. But I could still hear it. A soft rustling, like dry leaves scraping against glass. Then a knocking. Three slow, deliberate knocks, right on the pane, directly behind where I stood. ‘I said knocking,’ the voice whispered, muffled but clear. ‘You left it open so long. Now you’ll hear me every night. Until you finally come to the yard. And when you do, I’ll show you what the willow keeps.’
I spent the rest of the night huddled in my bed, every creak and rustle amplified. The knocking continued at intervals, sometimes gentle, sometimes violent, as if it were tapping a rhythm. When dawn finally broke, I peered through the blinds. The willow looked ordinary again, innocent, its branches draped languidly. But I noticed something I hadn’t before: a single, fresh gouge in the bark, deep and raw, as if a claw had scraped it. And embedded in the gouge was a strand of long, dark hair.
I never stayed another night in that house. I moved the next day, to an apartment in the city, with no trees near. But even there, in the heart of the concrete and steel, I hear it sometimes. A throat clearing, deep and wet, in the silence of my bedroom. And I know, no matter where I go, if I keep an open window, it will find me again. So I keep my windows sealed, the blinds drawn forever. But in the dead of night, I still feel the draft, as if something is breathing on the back of my neck, and I hear that patient, amused voice, whispering, ‘I left the window open for you. Just like you left it for me.’
