How about giving her a "Mystery Night In" gift basket? This can include a selection of her favorite mystery movies on DVD or a streaming service gift card to rent movies. You could also include a cozy mystery novel or two by her favorite author, a puzzle or a murder mystery board game to solve, and some movie night snacks and drinks like popcorn, candy, and soda. You could also consider surprises that enhance the atmosphere, such as a dimmer or flicker bulb, a scented candle or aromatherapy diffuser to add a sense of mystery and ambiance.
Or you can get her a star map with the date when she was born.
