Once upon a time there was a Pussy-cat called Ribby, who invited a little dog called Duchess, to tea.<br/>"Come in good time, my dear Duchess," said Ribby's letter, "and we will have something so very nice. I am baking it in a pie-dish-a pie-dish with a pink rim. You never tasted anything so good! And you shall eat it all! I will eat muffins, my dear Duchess!" wrote Ribby.<br/>Duchess read the letter and wrote an answer:-"I will come with much pleasure at a quarter past four. But it is very strange. I was just going to invite you to come here, to supper, my dear Ribby, to eat something most delicious.<br/>"I will come very punctually, my dear Ribby," wrote Duchess; and then at the end she added-"I hope it isn't mouse?"
