"Call Hussein," said Wonckhaus to the orderly, whom Frank had seen without observing.

The Arab entered. The orderly followed him, and stood in the background. Frank just glanced at him, and was surprised to see him raise a finger to his lips, then drop his hand quickly and stand motionless as before, looking, however, hard at Frank. Wonckhaus and the Arab had turned towards each other, or they might have noticed the slight start and the enquiring glance into which Frank had been surprised by the orderly's movement.

"The effendi complains of his food," said Wonckhaus. "What does he get?"

While Hussein, with a look of sly enjoyment, was retailing the list of the meagre rations supplied, the orderly drew from his tunic a watch, apparently of cheap European or American make. He did not look at it, but held it up, then glanced at the window in the wall above his head on the left. Wonckhaus, following Frank's eyes, turned round. The orderly was affecting to look at the time.

"You surprise me, Hussein," said the German. "The diet is more than liberal. How often during the past month should I and my brave men have been grateful for such rations! Ah! these luxurious English! They have lived on the fat of the land. And what is the result? They are degenerate; they have fed the body and starved the mind. They are learning their mistake. That will do, Hussein."

The Arab left the room. The orderly returned the watch to his pocket, holding it significantly suspended by the chain for a moment. Then he stared straight in front of him, unintelligent, impassive.

"Well now, Mr. Forester," said Wonckhaus, "the lot of a prisoner can never be quite comfortable, though it is preferable to the hard lot of the fighting man. If you feel discomfort, the remedy is in your own hands. I need not repeat the explanations which you received so churlishly at our last meeting. I will give you another week for reflection. At the end of that time--well, we shall see!"

CHAPTER VIII

A LEAP IN THE DARK

"What does it mean?" thought Frank, once more alone.
