Soldiers passed in and out, waiting on them.

"Coffee," asked Lupin.

They brought him some coffee.

"What bad stuff!" he grumbled. "If that's what Cæsar drinks! . . . Give me another cup all the same, Waldemar. We may have a long night before us. Oh, what vile coffee!"

He lit a second cigar and did not say another word. Ten minutes passed. He continued not to move or speak.

Suddenly, Waldemar sprang to his feet and said to Lupin, angrily:

"Hi! Stand up, there!"

Lupin was whistling a tune at the moment. He kept on whistling, peacefully.

"Stand up, I say!"

Lupin turned round. His Imperial Majesty had just entered. Lupin rose from his chair.
