Three girls—Pam, Beth, and Sue—attend a 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, and lots and lots of marble. Suddenly, the oldest girl, Pam, sees what can only be described as something truly . . . bilious . . . not good! Beth sees it too. The youngest, Sue, does not, and as usual, she has a hard time getting anyone to tell her anything. Party: A Mystery is a beautifully drawn adventure story that promises questions that will grab children, but does not guarantee an answer.
