I read the book around 2017. I forgot the author’s name. The book is a children mystery about a group of about 5 siblings ranging from the ages of 10-20. One morning they wake up and find that their parents are missing because they didn’t receive a note from them saying that are at work and safe like they usually do. Their parents might be spies because they often work late and leave for long periods of time. They find clues and use them to find their parents. Idk if the parents were found dead or alive. The book was set in the 2000s -2010s. I can’t remember the book cover, but the book was really thick. The book was in English.
