The Unseen Passage

My dog, Biscuit, came into my life on my tenth birthday, a wriggling ball of tan fur with eyes like polished chestnuts. He was my constant companion, my confidant, the one who listened without judgment. But as the years passed, I began to notice things about him that defied explanation, things that prickled at the edges of my sanity.

It started with small inconsistencies. I’d close the kitchen door behind me, knowing full well Biscuit was inside, and trudge up the stairs to my room. Yet, when I’d settle into my chair, I’d hear the soft thud of his paws on the landing, and there he’d be, sitting in the doorway, his head tilted as if he’d been waiting all along. The door was shut, I was certain of it. I checked the latch, the hinges, even the frame for any sign of weakness, but it was solid. Biscuit, a small Shih Tzu, couldn’t possibly reach the handle, let alone turn it. I chalked it up to my own absent-mindedness, a trick of the mind.

But then the incidents grew more frequent and more bizarre. One afternoon, I put him in the backyard, slid the bolt across the door, and went to watch TV. Half an hour later, I heard a whimper from upstairs, coming from the bathroom. I rushed up, my heart hammering, and found him sitting on the mat, his tail wagging as if he’d just performed a magic trick. The back door was still bolted from the inside, the bathroom window was shut and locked, and there was no dog flap. The only explanation was impossible.

I tried to rationalize it, to find some logical explanation. Maybe he was squeezing through some hidden passage, a gap in the walls, a forgotten duct. But the house was old, and I knew its secrets. There were no crawl spaces, no attics, no basement. The walls were solid plaster. Still, I couldn’t shake the feeling that something was deeply wrong.

One night, I decided to test him. I closed the bedroom door, wedged a chair under the handle, and placed a trail of flour across the hallway. I lay in bed, listening, my skin crawling with anticipation. I heard the soft patter of paws, then silence. In the morning, the flour was undisturbed, the chair still in place, and Biscuit was asleep at the foot of my bed. He had been there all night, I was sure. But the door was closed, and the chair was heavy. How?

I became obsessed, watching him, setting traps. I taped paper over the kitchen door, only to find it ripped from the inside. I installed a camera, but the footage showed nothing—just empty frames, then a blur, and he’d be on the other side. It was as if he could teleport, or as if the house itself was betraying me.

My mother thought I was losing it. She’d find me staring at Biscuit, my eyes wide, and she’d laugh, ‘He’s just a dog, honey.’ But I knew better. There was something else, something that wore my dog’s face.

Then one evening, I cornered him in the living room. I had closed all the doors, secured every window, and stood before him, my heart pounding. ‘How do you do it?’ I whispered. Biscuit just looked at me, his tail still, his eyes unblinking. And then, slowly, he turned and trotted towards the wall. I watched, frozen, as he walked straight into it, his body melting into the plaster like smoke. I stood there, staring at the blank wall, my breath caught in my throat. I ran my hands over the surface, feeling for a seam, a crack, anything—but it was smooth and solid.

I never saw him come back. I searched the house, called his name, but he was gone. The next morning, I found him in his bed, as if nothing had happened, but I knew. I knew he had been somewhere else, somewhere I couldn’t follow. I still live in that house, with my dog, my best friend. But now, when he stares at me with those chestnut eyes, I see the glimmer of something ancient, something that lives in the walls, using him as a vessel. And I wonder, every night, if one day he’ll walk into the plaster and never return, or if he’ll take me with him.
