Not one of my favourite Mandie stories, but was good anyway filled in a gap if you are reading the whole series. Seems Mandie had a harder time with that mystery than she did in her other books/stories.
Mandie is excited about going home for Christmas, but she hasn't told her grandmother that she invited Jonathan Guyer and his father to visit them during the holidays. Will Mrs. Taft be angry with Mandie because she doesn't get along with Mr. Guyer? And Mandie hasn't told Joe that Jonathan is coming, and the two boys haven't gotten along well either. Will Joe be upset with Mandie?
Then on a dark, cold night a mysterious gift is left on the doorstep of the Shaw house with an anonymous note attached that reads, "For Mandie." The box has fancy gift wrapping on the outside, but inside is what appears to be a childish jumble of holly and dirt and ribbons. Whatever could it be?
Who sent Mandie the present? Could it be a treasure map?
