Mrs. Frisby and the Rats of Nimh

When mouse widow Mrs. Frisby needs advice on how to move her children safely, she consults the rats who live under the rosebush. Not only do they help her, they tell her of their escape from a laboratory where experimentation had made them literate, and of the brave death of her husband.
