The Old Motel Mystery (The Boxcar Children Series #23)

Henry, Jessie, Violet, and Benny are in Florida with Aunt Jane, staying at an old motel that belongs to her friend Kay. The motel is so run down Kay thinks it must be sold, but the children want to help her save it. They get to work--pulling weeds around the tennis courts, scraping moss from the pool, hanging new curtains. But someone is trying to ruin everything--paint is stolen, oranges are dumped in the swimming pool, and the motel is flooded. Will Kay give up and sell? Or can the Boxcar Children solve the mystery in time?
