From my early years, when I devoured every Nancy Drew or Hardy Boy mystery I could find, to today, when I still love to read, what (and play!) detective.
My favorite detective movies are the old Thin Man Movies. Not exactly appropriate for the kids - but I love them!
Whether you are planning a detective theme party or mystery party, the theme will involve a mystery or scavenger hunt of some kind.
The mystery can also lend itself well for slumber party games, with a mystery or hunt happening throughout the evening.
Fun Detective Birthday Party Ideas:
Have everyone take their fingerprints, or do other "detective training" exercises.
Have a grab bag of disguise materials and let everyone create their own disguise. You could even play musical dress up as a fun way to create a disguise.
