'I wish you had, sir.' There was a change in his voice, and he looked at me almost pathetically.

'What's the matter?'

'Of course I have no right to say anything,' he said. 'Discipline is discipline, and I am only a private soldier. Are you busy, sir? If you are, I will go away. But, owing to this scratch, I am at a loose end, and—and—I'd like a chat with you, sir, if you don't mind.'

'Say what you want to say.'

He was silent for a little while, and seemed to be in doubt how to express what he had in his mind. I saw the old, yearning, wistful look in his eyes, too, the look I had noticed when we were walking on The Hoe at Plymouth.

'Has your memory come back?' I asked eagerly. 'Has it anything to do with that?'

'No,' he replied, 'my memory has not come back. The old black wall stands still, and yet I think it has something to do with it. I am afraid I forget myself sometimes, sir, forget that you are an officer, and I am a private.'

'Never mind about that now. Tell me what you have to say.'

'This war has shaken me up a bit, it has made me think. I don't know what kind of a man I was before I lost my memory; but I have an idea that I look at things without prejudice. You see, I have no preconceived notions. I am a full-grown man starting life with a clean page, that's why I can't understand.'

'Understand what?'
