After a hang glider crashes into the pool of the house where Dinah and Madge are house-sitting, the hapless pilot creates more than a splash of suspicion in Dinah's mind. Why does this itchy intruder make off with Dinah's inflatable turtle? Why is someone trying to drive their cat-mad neighbor away? And what is the connection with the stranger seen lurking behind the hedge? And when Madge's boyfriend starts a campaign to save an endangered owl, it seems that a crooked politician may be out to destroy the habitat of the near-extinct animal. While Madge paints, Dinah brushes aside suggestions that she be a quiet, well-behaved guest in this posh neighborhood. There's just too much for Dinah and her friends???tree-fanatic Pantelli and conscientious Talbot???to investigate in this hilariously suspenseful adventure. Along with learning about endangered animals, Dinah runs across bad reporters and greedy developers, all the while continuing to belt out her songs and satisfy her appetite.
