..What was this under her hands which was square and made of iron and which her finger found a hole in? It was the lock of the door which had been closed ten years and she put her hand in her pocket, drew out the key and found it fitted the keyhole. She put the key in and turned it. It took two hands to turn it, but it did turn. And then she took a long breath and looked behind her up the long walk to see if anyone was coming. No one was coming. No one ever did it seemed, and she took another long breath, because she could not help it, and she held back the swinging curtain of ivy and pushed back the door that opened slowly - slowly. Then she slipped through it, and shut it behind her, and stood with her back against it, looking about her and breathing quite fast with excitement, and wonder, and delight. She was standing inside the secret garden. - From author Frances Hodgson Burnett's The Secret Garden (1911)
