A few hours later I woke up again, to make sure it was all still true. The door was swinging open, moonlight and sea-sounds rushing in to fill up the caravan, and two bunks were empty. The note was on the table. I don’t remember what it said. Probably the police took it away; probably I could go looking for it in Records, but I won’t. All I remember is the P.S. It said, Dina is too little to do without her mum.

We knew where to look: my mother always loved the sea. In the few hours since I had been there, the beach had turned inside out, transformed itself into something dark and howling. A rising wind blustering, clouds scudding over the moon, sharp shells cutting my bare feet as I ran and no pain. Geri gasping for breath beside me; my father lunging towards the sea in the moonlight, flapping pajamas and flailing arms, a grotesque pale scarecrow. He was shouting, “Annie Annie Annie,” but the wind and the waves bowled it away into nothing. We hung on to his sleeves like kids. I shouted in his ear, “Dad! Dad, I’ll get someone!”

He grabbed my arm and twisted. My dad had never hurt any of us. He roared, “No! No one, don’t you bloody dare!” His eyes looked white. It was years before I realized: he still thought we were going to find them alive. He was saving her, from all the people who would take her away if they knew.

So we looked for them by ourselves. No one heard us shouting, Mummy Annie Dina Mummy Mummy Mummy, not through the wind and the sea. Geraldine stayed on land, up and down the beach, scrabbling through the sand dunes and clawing at clumps of grass. I went in the water with my father, thigh-deep. When my legs got numb it was easier to keep going.

For the rest of that night—I never figured out how long it lasted, longer than we should have been able to survive—I fought the current to stay standing and groped blind at it as it surged past. Once my fingers tangled in something and I howled because I thought I had one of them by the hair, but it came up out of the water a great lump like a chopped-off head and it was just seaweed, wrapping round my wrists, clinging when I tried to throw it away from me. Later I found a cold ribbon of it still bound around my neck.

When dawn started turning the world a bleak bleached gray, Geraldine found Dina, burrowed headfirst like a rabbit into a clump of marram grass, arms dug into the sand up to her elbows. Geri bent back long blades of grass one by one and scooped away handfuls of sand like she was freeing something that could shatter. Finally Dina was sitting up on the sand, shivering. Her eyes focused on Geraldine. “Geri,” she said. “I had bad dreams.” Then she saw where she was and started to scream.
