"And why must you go?" asked Atkins.

"My errand is a military secret."

"I hope you go well guarded?"

"I am to go alone."

Atkins started back and scanned him from head to foot. "It is very inconsiderate in you to tell this so openly," he said half aloud.

"I certainly should not tell it to the castle servants or to the villagers," said Walter. "I know you well enough, Mr. Atkins, to fear no treachery on your part."

"And have you told Henry?"

"Yes, as much as I have told you, nothing more!"

"This is German simplicity which I cannot at all understand!" muttered Atkins; then laying his hand on the young man's arm, he said with almost frightful earnestness.

"Lieutenant Fernow, follow my advice. Do not go to the mountains to-night. Your life is threatened; yours alone. Delegate this duty to one of your comrades."
