The Mystery of the Little Dancer (Kids Full-Length Mystery Adventure Book 4) #669264

Three kids in seventh grade named Luna, Milo and Axel were enjoying the school tour at the National Gallery of Art. The kids have been waiting for this day. Luna and Axel were playfully enjoying the sight of the displayed paintings and sculptures while Milo is laser-focused on each display, carefully reading all the descriptions of each historic 
masterpieces..
    The teacher calls the students to gather up as they will all have some snacks before the audio visual presentation starts. Milo tells Luna and Axel to head first at the museum canteen as he wants to finish looking at the few sculptures he hasn’t seen yet.
Milo was about to leave the display area after looking at all the sculptures  when he saw a suspicious man that seemed to be screwing something under the box table where the The Little Fourteen-Year-Old Dancer sculpture is displayed. He decided to tell what he saw to their teacher who then told the museum's manager what he saw. When Milo saw the suspicious man inside the manager’s office he immediately tells the manager that it is the man he saw but the manager just laughs and says he’s a staff member and is probably just working earlier. When the kids were about to leave the manager's office they heard the suspicious man and manager talking about their plan. Now the kids are certain that two are working together to try to steal the sculpture. The three young kids now don't know who they can ask for help, they know that the teacher wouldn’t believe their story but they need to do something to protect the historic sculpture from being stolen.
