"I was out," said the man shortly. "I get some time for myself, I suppose?"

The colonel nodded slowly.

"Sure you do, Hanson."

His tone was mild, and that spelt danger to Hanson, had he known it. This was the third sign of rebellion which the man had shown in the past week.

"What's happened to your temper this morning, Hanson?" he asked.

"Everything," exploded the man and in his agitation his foreign origin was betrayed by his accent. "You tell me I shall haf plenty money, thousands of pounds! You say I go to my brother in America. Where is dot money? I go in March, I go in May, I go in July, still I am here!"

"My good friend," said the colonel, "you're too impatient. This is not a moment I can allow you to go away. You're getting nervous, that's what's the matter with you. Perhaps I'll let you have a holiday next week."

"Nervous!" roared the man. "Yes, I am. All the time I feel eyes on me! When I walk in the street, every man I meet is a policeman. When I go to bed, I hear nothing but footsteps creeping in the passage outside my room."

"Old Jack, eh?" said the colonel, eyeing him narrowly.

Hanson shivered.
