'She wasn't thinking anything more about it, when two Sundays afterwards the very same thing happened just as it had before. This time aunt plucked up a spirit, and asked uncle what it could be. And what do you think he said? "Birds, my dear, birds." Of course aunt said to him that no bird that ever flew with wings made a noise like that: sly, and low, with pauses in between; and then he said that many rare sorts of birds lived in North Middlesex and Hertfordshire. "Nonsense, Robert," said aunt, "how can you talk so, considering it has followed us all the way, for a mile or more?" And then uncle told her that some birds were so attached to man that they would follow one about for miles sometimes; he said he had just been reading about a bird like that in a book of travels. And do you know that when they got home he actually showed her a piece in the "Hertfordshire Naturalist" which they took in to oblige a friend of theirs, all about rare birds found in the neighbourhood, all the most outlandish names, aunt says, that she had never heard or thought of, and uncle had the impudence to say that it must have been a Purple Sandpiper, which, the paper said, had "a low shrill note, constantly repeated." And then he took down a book of Siberian Travels from the bookcase and showed her a page which told how a man was followed by a bird all day long through a forest. And that's what Aunt Marian says vexes her more than anything almost; to think that he should be so artful and ready with those books, twisting them to his own wicked ends. But, at the time, when she was out walking, she simply couldn't make out what he meant by talking about birds in that random, silly sort of way, so unlike him, and they went on, that horrible whistling following them, she looking straight ahead and walking fast, really feeling more huffy and put out than frightened. And when they got to the next stile, she got over and turned round, and "lo and behold," as she says, there was no Uncle Robert to be seen! She felt herself go quite white with alarm, thinking of that whistle, and making sure he'd been spirited away or snatched in some way or another, and she had just screamed out "Robert" like a mad woman, when he came quite slowly round the corner, as cool as a cucumber, holding something in his hand. He said there were some flowers he could never pass, and when aunt saw that he had got a dandelion torn up by the roots, she felt as if her head were going round.'
