El cuadro secreto del Prado (Manuela Jones, 3)

Being the daughter of the directors of the National Archaeological Museum in Madrid can be quite a luxury: Manuela Jones travels the world and discovers incredible things, but she has to do it all with her twin brother, J.J., and, to make matters worse, without Wi-Fi! This time, Manuela won't be traveling too far: her school has organized a trip to the Prado Museum. But what seemed like a normal day soon turns into a dangerous adventure to stop a cunning thief who plans to uncover a secret hidden within the masterpieces of Velázquez and Goya.
