"Quite sure," said Betty vigorously. "I always know." She added with apparent inconsequence, "That's how it is we always get on so well. Are you going to take me right out on to the ramparts? Are you sure there will be no one else there?"
"There will be no one where we are going," he said.
She sighed a sigh of relief.
"How good! We shall get some air up there, too. And I want air—plenty of it. I feel suffocated."
"Mind how you go!" said Herne. "These stairs are uneven."
They had come to a spiral staircase of stone. Betty mounted it light-footed, Herne following close behind.
In the end they came to an oak door, against which the girl set her hand.
"Major Herne! It's locked!"
"Allow me!" said Herne.
He had produced a large key, at which Betty looked with keen satisfaction.
