Mary Poppins opens the door

Up in the sky a tiny spark hovered and swayed in the darkness. What could it be.? A classic original Mary Poppins novel.

Still they waited. And still the spark grew ever larger and brighter. Then suddenly Jane caught her breath. And Michael gave a gasp. Down came the spark, growing longer and wider. And as it came, it took on a shape that was strange and also familiar. Out of the glowing core of light emerged a curious figure - a figure in a black straw hat and a blue coat trimmed with silver buttons.
