The Magic Door

The thirty boys of Standard Three in a well-known Elementary School accidentally come into possession of a doorway into the past. An old metal knocker picked up near their playground proves to have magical properties; wielded in the empty air, it bangs on and then makes visible and tangible the door to which it belongs. Largely ignoring the warnings of the Winged Boy who acts as doorkeeper, the thirty boys go through the door and into stirring epochs of history.Usually hampered but sometimes assisted by their magnificently un-heroic teacher, Mr. Rocket, (with his nerves of steel), they discover that the past is fraught with danger.
