Some months ago I was brainstorming ideas of books to get for my friend's son who is a voracious reader. I remembered the Encyclopedia Brown books, which made me think that it would be fun to make detective kits for Christmas. So I have spent some time putting them together for him and my nephews and niece. I got Encyclopedia Brown box sets for the 9-year-old boys, I Can Read Berenstain Bear Mysteries for the 7-year-old, and a Strawberry Shortcake mystery for my 5-year-old niece who is obsessed with pink. Planning the boxes was so much fun. I designed ID badges and business cards, and also included fake mustaches, magnifying glasses, mini clipboards and notepads, and a really rad invisible ink pen that includes a light to read the messages. I think that these would be great favors for a mystery-themed birthday party.
