The Watsons have lost sight of the fact that Mercy Watson is a pig, and they love her truly, madly, deeply. They live next door to two elderly sisters, Eugenia Lincoln and Baby Lincoln. Eugenia Lincoln is horrified that a pig is living in the house next door. Baby Lincoln secretly likes Mercy a great deal.

Rats have a sense of humor. Rats, in fact think the world is very funny. And they are right, dear reader. They are right.

Reading a story should be a fabulous, wonderful thing. The most important thing that parents can do for kids is to read with them and to let their kids see them reading books for their own pleasure.

But it was, alas, put together wrong.

[A businessmen in plane after 9\11] asked me, "What are you working on now?" And I said I was writing a story about a mouse who tries to save a princess. I was mortified. Here the world is falling down around us, and I'm trying to tell the story about a mouse who saves a princess. I said "It doesn't matter at all now."
