How about buying him a puzzle-solving game or a mystery-themed board game, such as "Sherlock Holmes Consulting Detective" or "Clue"? Alternatively, you could get him a box set of classic mystery movies, like "The Maltese Falcon," "The Big Sleep," or "Chinatown." A subscription to a monthly mystery book club or a crime thriller novel by his favorite author could also be a great idea. Finally, you could organize a fun mystery date, where the two of you have to solve clues and puzzles to get to your final surprise location, like dinner at his favorite restaurant or a special activity that he enjoys.
Or you can get him a star map with the date of your first kiss.
