"Very well, sir," he said.

"I don't know that there is anything further," said General Rentzel,
"except to warn you that treachery means death."

"I am aware of that, sir," returned Hal quietly.

"Very good, then. Good luck to you."

The general moved away.

Hal sought Chester instantly, glancing at his watch as he passed along
slowly and without apparent haste. It was 10:30 o'clock.

"It's time to get busy, Chester," he said quietly. "It's half-past
ten, and I may require an hour and a half. You get word to Gladys and
her mother to keep General Rentzel here under some pretext until
midnight. I'm off."

"Am I not going with you?" demanded Chester.

"No," said Hal. "I don't have time to wait, and the message must be
delivered to Mrs. Schweiring or her daughter at once. I'll pick
McKenzie up on the way. Good-bye."

"Good luck," said Chester simply.

Hal left the room quietly. In the hall he found McKenzie, whom he
motioned to follow him. McKenzie did so quietly.
