Three girls  – Pam, Bess, and Sue – attend a book party to celebrate the publication of the first of the Nancy Drew mystery books. There are many distractions at the fancy affair: flower arrangements, partygoers, refreshments, cake, and lots of marble. Suddenly, the oldest girl, Pam, sees what only can be named as something truly... bilious... not good! Bess sees it too. The youngest, Sue, does not, and as usual, has a hard time getting anyone to tell her anything.

Party • A Mystery  is written by the acclaimed award-winning novelist, essayist, professor, and gardener, Jamaica Kincaid. The book is illustrated in color pencil by #1 New York Times best-selling illustrator, author, and artist, Ricardo Cortés. Party • A Mystery is their first book together.
