The Mysterious Halloween: The Peebody Agency - Book 4

By Joe Egly

Halloween is supposed to be all about fun-costumes, candy, and the big parade. But for Charlotte Peebody and her detective team, this year brings a mystery they can't ignore.

It starts with strange costume swaps-clever but unsettling changes that leave students confused and more than a little uneasy. Then Charlotte finds the most disturbing clue of all: a handmade mask of her own face... wearing a smile that doesn't belong to her.

With the parade just days away, the Peebody Agency dives into the case, following a trail of hidden clues, suspicious behavior, and tense encounters backstage. Someone is determined to make this year's Halloween one nobody will forget-and it's up to Charlotte and her friends to unmask the culprit before the final float leaves the gym.

The Mysterious Halloween is a clever, clue-filled middle grade mystery full of teamwork, humor, and just the right amount of spooky atmosphere-perfect for readers ages 8-12 who love solving puzzles right alongside the characters.
