An afternoon for curious minds

Two mysteries. One detective team.

Join Evelyn, Elliot and Ozzy at Hollow Hall. Ada has locked the parade lantern in the tower case for her Halloween trail. Follow clues, solve four puzzles and collect the letters that open it. Meanwhile, something pale is moving at the landing window. Inspect objects and connect four observations to explain what you have seen.
