Alice in Wonderland by Lewis Carroll

Alice was sitting on the bank when a White Rabbit hurried close by her, saying to itself, "Oh dear! Oh dear! I shall be late!"
She ran after it and was just in time to see it pop down a large rabbit-hole. In another moment down went Alice after it . . . 

The story of what happened to her down the rabbit-hole is one of the best-loved tales of all time. Who could forget the Mad Hatter, the March Hare and the Cheshire Cat - or the Duchess with her sneezing pig-baby, the tearful Mock Turtle, and the ruthless Queen of Hearts, forever shouting, "Off with her head!"

As Alice would put it; "Curiouser and Curiouser. . . "
