A great anniversary gift for your girlfriend who likes mystery movies could be a mystery puzzle game that she can spend time playing and solving. You can also consider gifting a subscription to a mystery book club or an online streaming service that features mystery movies and shows. She might also appreciate a book or movie of her favorite mystery author or director, or even an interactive murder mystery game that you can do together. You could also organize a surprise mystery date night complete with puzzles to solve, clues to find, and a special dinner or movie screening. These gifts will definitely show how much you care about her interests and passion for mysteries.
Or you can get her a star map with the date of your anniversary.
