From the Mixed-Up Files of Mrs. Basil E. Frankweiler

　　Claudia決定要離家出走了！但她可不像普通小學生那樣一氣之下衝出家門，早熟細膩的她一向喜歡凡事舒服、計劃妥當，她早就擬妥離家出走的預定地：紐約大都會美術館。事情發展似乎正如計劃般的順利，然而就在Claudia姐弟正舒服躺臥於十六世紀的皇家御用床時，他們卻意外捲入了天使雕像的秘密中：美術館剛自Frankweiler夫人收藏品中廉價購入的天使雕像，究竟是否為文藝復興大師米開朗基羅的傑作呢？如果是的話，美術館無疑達成了史上最便宜的交易?och Elaine Konigsburg以幽默風趣的筆調，敘述Claudia姐弟藏身於美術館中的趣味過程。全篇以Frankweiler夫人的書信作為旁白倒敘，大人觀點與小孩世界於其中親切互動。這不僅是一部精采的歷險故事，更是一部探討青澀成長與自我認識的好書。

2017 marks the fiftieth anniversary of the beloved classic From the Mixed-up files of Mrs. Basil E. Frankweiler.

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.
