“Around 2014-2015, might be year of production around 2010. I saw a movie that was about a recently dead grandfather that wasn’t really dead. It took place over Christmas in a winter cabin, he had a granddaughter that was good in solving riddles and she was the first that discovered he still lived. It had a riddle with a music box that was disguised as hidden in the Christmas tree. They had to enter the melody into a not working clock on the wall and it opened and it had a key inside. It had hidden rooms and other such things. The grandpa was watching everyone on cameras and when she discovered him, she joined him and they worked together with her in disguise. I think it had something to do with inheritance or maybe they wanted to kill him. I also remember he had a very old butler helping him that was kinda shady in the end. If anyone could help me I would appreciate it, I have been looking for it for like 5 years. Thanks”
