The story is about a woman, I think her name was Maya, who found a letter in an old book at some historical place. The letter was really old, from the 1920s, and it talked about a key being hidden somewhere at a lighthouse. She went to the island where the lighthouse was, and it was all run down with peeling paint. She dug around some stones and found a brass key. Then she tried the door but it didn't work, so she looked around and found another small door hidden behind some plants. She went inside and there were stairs going down into a cave or room underground. The room had jars on shelves with things from the ocean and a desk with a notebook that had drawings of sea creatures. The notebook had a message about continuing to watch the sea. I remember she called someone on the phone at the end to tell them what she found.
