The Mystery of the Louvre’s Puzzle (Kids Full-Length Mystery Adventure Book 1) #669261

Freya and Frida are enjoying the day in the Place du Carrousel while their parents are busy preparing for the Fashion week. Frida left Freya sitting at the bench to buy some drinks when Freya, just out of curiosity wrote the jumbled letters she saw from the group of suspicious people seated beside her.
    Back in the hotel room, Freya told Frida about the group of people she saw earlier and showed Frida the jumbled letters she jotted down on her book. With nothing else to do that night the two decided to decode the letters that lead them to the second clue. The next day the twins found themselves in the middle of a hunt with a detective and police. 
    Both of the  twins know that it's a dangerous mission they’re taking but they  also know that they are needed to be a part of it to finally put the criminals behind bars and save everyone’s life at potential danger.
