The Magic Door by Dan Billany     Thomas Nelson & Sons 1943

      ... Perhaps they were the noisiest set of boys you ever saw; or perhaps not, but they got more opportunity.

    Dan's class, Standard Three at Chiltern Street School inspired The Magic Door, a story about a class of boys and their teacher, Mr. Rocket.

      "What a foolish door-knocker that would be," said Mr. Rocket, with a gentle smile. "You mean - hold it up like that," he held up the little piece of metal, "and then bang it - so." He banged with it as he spoke, and then an amazing thing happened; as he moved the piece of metal twice forward, from empty air came two tremendous knocks, just as if he had knocked on an iron door. Mr.Rocket, who had nerves of steel, suddenly remembered a book he wanted for the next lesson and hurried to the cupboard to get it ...When Mr. Rocket looked round he saw an amazing sight. There, standing in the wall of the room and cutting through the middle of the blackboard, ... was a splendid door, made of shining green metal, with black scroll work on it, and a decorated archway round it, with precious stones flashing in the pattern of the decoration ... And with a grinding, creaking, squeaking, metallic noise from its enormous hinges the great door was swinging open ...
        

Through the arch beyond which shone a strange attractive light, strode swiftly and silently the figure of a boy ...From his shoulders rose two silver wings, which were so big they swept up level with his head and then down again almost to the floor. His heels were also winged - Mr.Rocket thought that was too much of a good thing - and he wore sandals of gold.
       "What is your will?" he cried.
      Mr. Rocket could not think of anything to say; and glancing doubtfully at his watch, he said: "Can you tell me the right time?"
       "It's always the right time," said the boy.

       In The Magic Door the Winged Boy is the son of Time; with far too much it on his hands.

       The boys of Standard Three, and their teacher Mr.Rocket  get into all sorts of trouble when he takes them through the Door of Time on many a dangerous journey through the centuries.

       ... "Well, how do you like going into history?" asked the Winged Boy.
