When suburban Claudia Kincaid decides to run away, she knows she doesn’t just want to run “from” somewhere, she wants to run “to” somewhere — to a place that is comfortable, beautiful, and, preferably, elegant. She chooses the Metropolitan Museum of Art in New York City. Knowing that her younger brother Jamie has money and thus can help her with a serious cash-flow problem, she invites him along.
Once settled into the museum, Claudia and Jamie find themselves caught up in the mystery of an angel statue that the museum purchased at auction for a bargain price of $225. The statue is possibly an early work of the Renaissance master, Michelangelo, and therefore worth millions. Is it? Or isn’t it? Claudia is determined to find out. Her quest leads her to Mrs. Basil E. Frankweiler, the remarkable old woman who sold the statue, and to some equally remarkable discoveries about herself.
