In another edition of the Boxcar Children, the four children have earned reputations as first-rate detectives and are in a competition with another family of kid detectives.  The other family, the Best family, have won this competition four times and are looking forward to their fifth win, earning them an all expense paid trip to Hawaii.  Right from the start, their Aunt Fiona, tries to sabotage them by mismarking landmarks on maps, stealing a  precious object from Benny, and by spying on them and then telling her nieces and nephews their clues.  The Alden children are pretty smart and catch on to her antics.  I really enjoy this series because of it’s readability and consistency.
