“Just you leave the moon alone!” cried the wild little voice from the Night Watchman’s box in the Square.

Everybody turned to look. What they saw was a small fierce figure in an old top hat and a long-tailed coat dancing excitedly round and round the roped-in enclosure. In one hand he had a telescope, and in the other a pair of field-glasses, both of which he flourished in the direction of the Balloon Woman.

“You would, would you?” he shrilled. “Come out o’ that, you Mrs. Green.

“Oh dear, oh dear,” said Ginger. “I’m afraid this is all my fault.” She hurried to the enclosure. “Please do be quiet and tell me why you don’t want me to have the moon.”

“The thoughtlessness of the young!” said the little man, mopping his brow with a blue handkerchief dotted with white stars. “It’s all on account of the likes o’ you that the likes o’ me has to watch the night. A nice mess she’d get into otherwise.”

“I’m so sorry. Come and have a sausage,” coaxed Ginger.

He shook his head. “Can’t,” he said shortly. “What d’you suppose the rope’s here for?”

“To keep us out,” suggested Ginger.

“To keep me in,” said the wild little man. “Set a thief to catch a thief, and one that never knew his place to keep the night in hers. Ah, many and many a time They’ve set me to watch her because They knew I’m up to all her tricks. But They have to coop me in, or I’d be off. On land They put a rope round me; on sea They put me up the mast.”

Ginger beckoned to the others, and they gathered round from the Weatherhouse. Gypsy brought the teapot with him, and the Night Watchman was given a cup across the barrier.
