Okay so this is an english movie that I saw ages ago and involved a little boy and his family going to their Grandmas home (I am also relatively certain the grandmother was dead). The home was on a Cliffside and the boy ended up in the grannies library and there was magic and stuff. I also remember a lot of beach themed stuff so if this was actually a movie and not some weird fever dream I’d have to guess that it probably took place around a beach. Later on in the movie he ends up in a concinment store sort of place where he’s searching for clues of some sort. Im sorry I know this isn’t very clear but if anybody could point me in the right direction I would be most grateful!
