The front door stood wide open so that the moonlight made a bright splash between the dark walls. Rebecca Mary and Granny reached the threshold in safety. It only remained to dash across the lawn, climb the fence and turn up their noses at the authority of fat Major Martingale who had said no one could leave Riverside. The shrubbery would conceal them for more than half the way. Granny's hand relaxed, and she stopped breathing like a spent porpoise.

"I do believe we'll make it," she whispered excitedly.

And then she gave a little scream, for out of the shadow made by a white lilac emerged a short fat figure, and a curt voice asked them where they were going.

"Oh, Major Martingale!" Granny's voice quavered. "I thought you were at the shop with the other men. Whoever would have expected to meet you here!"

"Evidently you didn't." The Major was all grim suspicion. "May I ask where you are going?"

Granny pinched Rebecca Mary's arm. "It was so warm upstairs that we came down for a breath of air," she explained with a little sniff of defiance, as though she dared him to object to their desire for air.

"I'm glad you put on your hats and brought your baggage," remarked the Major coldly, and he glanced significantly at the umbrella and the bag. "Night air is so deceptive, you can't tell when you will need an umbrella." He looked at the cloudless sky. "Or extra clothing." He wiped the perspiration from his hot forehead.

"Yes, isn't it!" Granny emulated Moses and was as meek as meek, butter would not have melted in her mouth just then. "Come, Rebecca Mary. Good-night, Major Martingale." And with Rebecca Mary's hand in hers she turned to the terrace as if she really had come down all hatted and coated for a walk in the moonlight.

"If it is so warm upstairs I shan't go to bed yet." Major Martingale fell in at her other hand. "I'll walk with you."
