The Little Ghosts are awoken one morning by a strange banging sound coming from... Oh no! Not the cellar! Torch in hand, Henry, George, Lucy and Edward go to investigate. The noise is coming from behind a very small door, and the Little Ghosts decide to open it together. One... two... three... it was only Aunt Gigi all along! Full of surprises as usual, Aunt Gigi is mending an old suit of armor, surrounded by what look like wonderful costumes. "Oh, but these are not costumes," corrects Aunt Gigi, "these are clothes worn by our ancestors." George finds a pirate's hat, and before you can say, "Shiver me timbers, you've kidnapped me parrot," the Little Ghosts are all dressing up and having a magical time.
