                Claudia Kincaid has decided to run away from home. But she will not just run away - she will run to the Metropolitan Museum of Art with her brother Jamie because 1) he keeps quiet 2) he's richer than she is and 3) he has a transistor radio. Once there, the two establish a secret life, one that's like no other. Then they find Angel. Claudia feels she cannot go home until she finds out the secrets of Angel - and that is harder than it looks. Going for Angel's previous owner, the two hope to uncover the secrets they wish to find.
                  The hardest part for the Kincaid siblings was to live in secret. How did they manage this? Where did they get their income? Did they ever come home? Find out in Koningsburg's award winning classic, From the Mixed-Up Files of Mrs. Basil E. Frankweiler!
