It is summer and Ann is spending her vacation with her parents in majestic Fundy National Park. Driving to the campsite, the periodic fog seems to play a trick on them as a truck appears out of nowhere and thunders past, almost bulldozing their motor home off the road. What a frightening greeting of their arrival! Anne and Higgins, her Golden Retriever, will not have anything in the way of having fun, exploring the vast park, and making new friends especially with Bart, the friendly boy at the pool. Not even Rachel who is playing tricks on her will dampen her good spirits. Yet the atmosphere in the campsite turns sinister as Sam, a young man, goes missing on the second day, leaving a distraught sister alone in tears. Everyone believes he has fallen off the cliff and into the deep and churning tide of Fundy bay. Ann herself had seen him and Henri, the grounds keeper and reckless driver, arguing in the shadows near the cliff. Henri seems to hate everyone in the park and could not be trusted. Ann was curious to explore the history and wildlife in the park especially of the birds but the mysterious disappearance of Sam seems to absorb her. Could she be on a detective mission as she stumbles upon clue after clue? Could she be in danger for getting closer to the truth? Join Ann and her trusty Golden Retriever, Higgins, on a summer of self-discovery and participation in a triumphant criminal arrest.
