"Well, why are we allowed to sit here in solitary glory?" asked Frank.
"Ask me something easy," returned Jack. "We're here; that's all I know about it. However, I don't imagine we shall be here alone very long."
And he was right, although the first corner could not possibly have been in his mind, nor the nature of his coming.
Jack's attention was attracted toward the window by a slight squeaky sound. The lad glanced toward it, but no second sound followed immediately.
"Sounded like some one at the window," he said to Frank.
"I didn't hear anything," said the latter.
A moment later the noise came again. Jack sat up straight in his chair.
"Hear that?" he asked.
Frank nodded affirmatively.
"Some one there, all right," he agreed.
