"Miss Catherwood is still here, is she not?" repeated Prescott. "I assure you that I came in her interest."

Miss Grayson gave him a look of such keenness that Prescott saw again the strength and penetration underlying her timid and doubtful manner. She seemed to be reassured and replied:

"Yes, she is here. I will call her."

She disappeared into the next room and presently Miss Catherwood came forth alone. She held her head as haughtily as ever, and regarded him with a look in which he saw much defiance, and he fancied, too, a little disdain.

"Captain Prescott," she said proudly, "I am not an object for military supervision."

"I am aware of that," he replied, "and I do not mean to be impolite, Miss Catherwood, when I say that I regret to find you still here."

She pointed through the window to the white and frozen world outside.

"I should be glad enough to escape," she said, "but that forbids."

"I know it, or at least I expected it," said Prescott, "and it is partly why I am here. I came to warn you."

"To warn me! Do I not know that I am in a hostile city?"
