Help Nancy and her friends find out what happened to a superstar’s flower hat in the ninth book in the interactive Nancy Drew Clue Book mystery series.

Spring has sprung in River Heights! The annual Flower Sculpture contest is in a couple of days and everyone in town is working hard to finish their floral works of art. But Nancy, Bess, and George are most excited to see the world-famous pop singer, Miss LaLa, perform. The superstar grew up in River Heights and has agreed to kick off the contest with a song. And just when the girls thought life couldn’t get any better, they run into Miss LaLa herself! The singer is in a bit of a pickle though: She brought a giant hat made of white peonies for the show but she doesn’t have a refrigerator big enough to store it in. George thinks quickly and offers to put it in her mom’s catering refrigerator.

But when the girls check on the hat the next morning they see something has gone terribly wrong. Half of the snowy white blooms are wilted and brown! They use their detective skills to rule out a blackout. And George can’t remember if she locked the door last night. Could someone have snuck into the kitchen and switched the fresh flowers with droopy ones?

Nancy and her friends are determined to find out! Could it be Madame Withers, whose signature wilted rose perfume was rejected by Miss LaLa? Perhaps it was the famous flower artist Pierre, who was angry that Miss LaLa was the star of the show. Or it maybe it was Benjamin Bing, who ruined his flower sculpture with brown hair spray and had no more white peonies to replace them. It’s up to the Clue Crew—and you—to find out!
