Warm Stone, Cool Shell
"Why is the water warm here and cold there?" Suri asked. She stood knee-deep in the shallows with Mo beside her. The sun had been on the sea all day. Near the sand it felt like bathwater. Out past the rocks it felt like morning. Mo turned his old head slowly and blinked at her. Suri wiggled her toes in the warm part and laughed. Mo paddled one flipper, and a cool ribbon of water curled round her ankles.
Suri reached into her pocket and pulled out her flat grey stone. She had found it that morning on top of the tall rock. It had sat in the sun all day, and it had kept every bit. She held it against her palm. The warmth went right through her hand and up her wrist. "Feel," she said, and let Mo lean his cheek on it. Mo held very still. His eyes closed most of the way.
The sun slid down behind the rocks. The water round Suri's knees turned a little cooler. Mo swam to the flat stone shelf where he liked to rest. The last warm patch of sun had been there in the morning. Now the tide lay over it, grey and quiet. Mo climbed up anyway and tucked his head in. Suri waded over and sat down beside him. The shelf felt cool as a plate. She put her hand next to his flipper and waited.
Suri looked at Mo. Then she looked at the stone in her hand. It was still warm. It had been warm since breakfast, and it did not seem to mind who held it. Mo was slow and old and fond of warm places. Suri had two warm hands and a woolly jumper up on the sand. She turned the stone over once. "You could keep this," she said. Mo opened one sleepy eye. The water made small sounds against the shelf.
Mo slipped off the shelf into the shallows. He dug his nose into the sand and pushed. Up came a shell, pale as the moon, curled like a little wave. Suri picked it up. It had been under the wet sand all day, and it was cold as a stone from a stream. She pressed it to her warm cheek and gasped, and then she laughed. "Oh," she said. "Oh, that is lovely."
Suri set her grey stone down in the hollow under Mo's chin. Mo shifted until it fit. Then she closed her fingers round the moon-pale shell and held it tight. "Warm for you, and cool for me," she said. Mo let out a long breath through his nose. The stone gave its heat to him, slow and steady, the way the sun had done. Suri's cheek stayed cool where the shell had been.
They stayed on the shelf while the sky went the colour of plums. Little fish came to look at Suri's toes and went away again. The tide crept up, warm on top and cool underneath. Suri turned the shell over and over in her hand. Mo's shell was warmer than before. She leaned against it. "Warm for you, and cool for me," Suri said again, softer. The moon came out and lay down flat on the water.
Suri's eyes began to close. The shell in her hand had gone the same warmth as her fingers now, and she did not mind. Far out, something big and slow rolled over and breathed. The water moved past her knees, then past her ankles, then back again. Mo stretched his neck out and looked at her for a long moment. Then he tipped his shell sideways, close to the sand, and waited. Suri knew what that meant.
Suri climbed on. Mo carried her along the warm shallows, slow as a cloud. The water was silk. Her hand hung down and trailed a line through the moon. "Warm for you, and cool for me," she said into his shell. Mo did not hurry, because Mo never did. He set her gently on the dry sand, where the heat of the day was still kept. Somewhere behind them, the sea turned over in its sleep.
