"Let us say ten, monsieur," Burton pleaded. "It is, you will admit, a serious matter."

"Ten, then; not a minute more."

At the end of the ten minutes the captain called for an answer.

"The general wishes to know, monsieur, what guarantee he has for safety."

"The word of a German officer," snarled the captain. "Be quick!"

Waiting a minute or so, Burton said--

"The general has a little difficulty in making up his mind--pardonable at his age. You give him another ten minutes, monsieur?"

"Three; not a second more," cried the German, completely hoodwinked by Burton's tone, and unaware of the vital consideration in Burton's mind--the return of Captain Rolfe to head-quarters.

"Very well, monsieur. I will bring the general's answer in three minutes."

The marquise and Pierre were holding their breath. The same thought possessed them both; to what lengths would this audacious Englishman go?
