The hand that had touched his shoulder was deliberately transferred to his elbow.

“Come!” said his acquaintance, smiling a little.  “We are blocking the gangway.  I am staying at the Grand.  If you are at liberty you might dine with me.  By the way, how are you, old fellow?”

He spoke very quietly and wholly without affectation.  There was a touch of tenderness in his last sentence that quite restored Derrick’s faculties.

He shook his arm free from the other’s hand with a vehemence of action that was unmistakably hostile.

“No, thanks, Colonel Carlyon!” he said, speaking fast and feverishly.  “If I were starving, I wouldn’t accept hospitality from you!”

“Don’t be a fool!” said Carlyon.

His tone was still quiet, but it was also stern.  He pushed a determined hand through Derrick’s arm.  “If you won’t come my way,” he said, “I shall come yours.”

Derrick swore under his breath.  But he yielded.  “Very well,” he said aloud.  “I’ll come.  But I swear I won’t touch anything.”

“You needn’t swear,” said Carlyon; “it’s unnecessary.”

And Derrick bit his lip nearly through, being exasperated.  He did not, however, resist the compelling hand a second time, realizing the futility of such a proceeding.

So in dead silence they reached the Grand and entered.  Then Carlyon spoke again.

“Come up to my room first!” he said.

Derrick went with him unprotesting.

In his own room Carlyon turned round and took him by the shoulders.  “Now,” he said, “are you ill or merely sulky?  Just tell me which, and I shall know how to treat you!”

“It’s no thanks to you I’m not dead!” exclaimed Derrick stormily.  “I didn’t want to meet you, but, by Heaven, since I have, and since you have forced an interview upon me, I’ll go ahead and tell you what I think of you.”

Carlyon turned away from him and sat down.  “Do, by all means,” he said, “if it will get you into a healthier frame of mind!”

But Derrick’s flow of eloquence unexpectedly failed him at this juncture, and he stood awkwardly silent.

Carlyon turned round at last and looked at him.  “Sit down, Dick,” he said patiently, “and stop being an ass!  I’m a difficult man to quarrel with, as you know.  So sit down and state your grievance, and have done with it!”

“You know very well what’s wrong!” Derrick burst out fiercely, beginning to prowl to and fro.

“Do I?” said Carlyon.  He got up deliberately and intercepted Derrick.  “Just stop tramping,” he said, with sudden sternness, “and listen to me!  You have your wound alone to thank for keeping you out of the worst mess you ever got into.  If you hadn’t gone back in a hospital truck, you would have gone back under escort.  Do you understand that?”

“Why?” flashed Derrick.
