The Last Tidal Pool

My grandmother raised me in a crooked little house on a cliff above the North Sea. The wind never stopped moaning through the cracks, and the salt ate the paint off the shutters. We had a cat, Marlowe, a gray tom with one torn ear and eyes like cold green glass. He was old before I was born, so I never knew a time without him. He moved through the house like a tide, always present, always watching. When I was a baby, my grandmother said, he would sit in the corner of my crib, not touching me, just a sentinel. As I grew, he would follow me down the winding path to the cove, but never close enough to touch. I learned to talk to him in a low, sing-song voice, and he would answer with a gravelly trill that seemed to come from somewhere deep and dark inside him. When I cried, he would press his cold forehead against my cheek and knead his claws into my lap, purring like a storm churning far out at sea.

When I was twelve, Marlowe began to dwindle. He stopped chasing the gulls that laughed from the rocks. He would stagger a few steps and then sink down, front legs folding, chest heaving. The vet came one day, a woman with hands that smelled of antiseptic and dead things. She took Marlowe into the back of her van, and when she came out, her face was grim. ‘His kidneys are failing,’ she said to my grandmother. ‘It’s a mercy to let him go.’ My grandmother nodded, her thin lips pressed into a line. She chose to have it done at dusk, when the tide would be low and the cove empty. ‘He was a creature of the ebb,’ she said, as if that explained it.

That afternoon, I sat with Marlowe on the porch steps. He lay in my lap, his fur rough and matted, his stomach heaving with each breath. He stared out at the sea, and I stared with him. The water was a grey-green that seemed to absorb the light. I couldn’t stop the tears. They dripped onto his head, and he didn’t even flinch. I buried my face in his warm, sour-tasting fur and said, ‘I love you, Marlowe. I always will.’ He made a sound I had never heard before, a deep, rattling purr, and then he was still. I thought he had died right there, but he twitched and opened his eyes, and they looked at me with an intensity that made me feel like he was speaking without words.

At the vet’s office, they placed him on a steel table. The vet was a kind woman, but her eyes were detached. She explained that she would give him an injection, and he would just go to sleep. I held his head, feeling the faint vibrations of his voice in his throat, a constant low rumble. The needle went in, and for a moment, his eyes flew open wide, and he let out a sound like a seagull’s cry, but lower, like something from the deep. Then his body relaxed into a stillness I had never felt before. The vet said, ‘He’s gone.’ But I didn’t believe her. I felt something leave the room, a cold draft that smelled of low tide and seaweed, and I swear I heard the sound of his purring, but it came from outside, from the direction of the cove.

We buried him in a patch of sand at the edge of our garden, under a dead arbutus tree. That night, I woke to the sound of the tide, which I always heard, but it was louder, closer. I walked to the window. The moon was full, and the water was silver-black. In the middle of the cove, just beyond the breakers, I saw a shape. It was Marlowe, standing on the water, his tail high, watching me. I blinked, and he was gone.

In the weeks that followed, the sea began to recede. The tide went out further and further, exposing rocks that had never been seen in my lifetime. The beach grew, and the cove became a strange, lifeless plain of sand and kelp. The gulls disappeared. The sea’s voice thinned to a whisper. My grandmother grew weaker, too, her cough growing wet, her eyes more distant. She would stand at the edge of the cliff and stare at the receding water. ‘He’s calling them,’ she said one evening, her voice barely a scrape. ‘He was always the guardian. Now they can come.’

I didn’t understand until the night I walked down to the cove. The moon was new, and the sea was just a black line at the horizon. The sand beneath my feet was cold, like stone. In the deepest hollows, left by the outgoing tide, there were pools of water, each one perfectly still. And in each pool, there was a reflection of the moon, even though the moon was dark. I knelt beside the largest pool. The water was black, and in it, I saw Marlowe’s face, not the old, sick cat, but a younger Marlowe, sleek and glistening, his eyes burning like lanterns. He opened his mouth, and a sound came out that was not a meow, but a deep, resonant hum that vibrated in my bones. I felt a tug, a pull, like the undertow dragging at my feet. And I knew: he wasn’t dead. He had just gone back to the sea, to the place from which he had come, and now he was waiting. He was always waiting. He would never let me go.

I dragged myself back up the cliff as the tide began to return, but it wasn’t the tide I knew. It was a black water that moved against the moon, and it carried a sound, like the purring of a hundred cats, low and hungry. My grandmother was gone from the house. I searched for days, but the only trace was the fresh, wet sand leading from the cliff edge down to the shore. And at the bottom, in the last remaining tidal pool before the water swallowed the cove, I saw her face, white as bone, her eyes open and fixed on me, just as Marlowe’s had been.

Now I sit by the window, watching the sea. The water never reaches the old high-tide line anymore. The cove is a vast, dark plain, and when the moon is out, I can see the pools scattered across it, like stars that fell to earth. And in each one, I see a reflection that is not mine. I see Marlowe’s eyes, and my grandmother’s face, and I hear the hum that is not a purr but a summoning. I know that one night, when the tide is right, I will walk down there, and I will step into the last tidal pool, and I will join them. And I will be the next guardian, waiting for the moon to set, and for the sea to drain away. That is what it means to be loved by a creature of the ebb. You become part of the tide.
