He made no reply, but I could see that his mind was busily at work.

'You remember that chap who got you out of that hole the day before yesterday?' he asked.

'What, Edgecumbe? I should think I do!'

'I hear he is missing.'

'Edgecumbe missing? Taken prisoner, you mean?'

'I don't know. I have not heard particulars yet. I should not have heard anything about him at all, but for the way he brought himself into prominence over that affair. But it seems he was last seen fighting with two Huns, so I expect he is done for. Terrible pity, isn't it? I was going to recommend him for decoration, and—and other things.'

In a way I could not understand, my heart grew heavy; I felt as though I were responsible for it, and that I had failed in my duty. And I had a sort of feverish desire to know what had become of him.

'Good night, colonel,' I said suddenly, and I hurried away into the darkness. I felt that at all costs I must find out the truth about Paul Edgecumbe.
