Trenchcoat Twins Case Report...from Mary-Kate & Ashley Surf's up, dude! When Ashley and I went on vacation to Mirale Beach, we couldn't wait to take surfing lessons. But we never expected to have a mystery crash right at our feet! A girl named Tiffany bragged that she was going to win the big surf contest--but somebody wanted her to wipe out! Tiffany got a scary note: Stay out of the water--or else! It was up to the Trenchcoat Twins to catch the creepy letter-writer...so Tiffany could catch a wave.
