Karl has emerged from the obscurity in which for years he has been wrapped and has become a topic of conversation, a link with the past, a popular alien enemy and a common nuisance.

Once upon a time, when we were first told about Karl, those of us who didn't say that it was an extraordinary coincidence observed that the world is a small place after all; but now, when the narrator reaches that part of the story where he tells us that we "can imagine his surprise when"—I usually interrupt him to say that he must forgive me, but really I cannot.

Karl was a German waiter at all the restaurants where my friends and my friends' friends were in the habit of dining. In time of peace not one of our mutual friends ever mentioned Karl to me, nobody ever wrote excitedly to tell me that they had seen him getting into a bus in the Strand; but now——

My sister-in-law's brother has the distinction of being the first among us to meet Karl since the outbreak of war. He was at Waterloo Station one morning when some German prisoners were being brought through from——, and as he passed them someone, speaking with a familiar voice and a strong German accent, addressed him by name. You can imagine his surprise when——

Karl, my sister-in-law said her brother told her, had spoken of being pleased to be among us once more, but this was apparently only another German lie, for when next I heard of him he was back in the trenches again. A friend of my brother's fiancÉe, who was superintending the removal of some German wounded to Paris, was surprised to find himself addressed by name by a young German whose face seemed vaguely familiar. You can imagine his astonishment when, etc. Karl, my brother said the friend of his fiancÉe told her, was only too glad to have fallen into English hands.

It was in a hospital ship in the North Sea that my cousin met him. The situation remained unchanged. He addressed my cousin by name and said he was longing to be back in England again.

Two days afterwards I heard that a friend of mine had seen him in Holland, where the unlucky fellow was interned, having deserted with the intention of returning to us.

I made it my business to let my friends know—those friends of mine who had not already heard from someone who had met him—that he was securely interned in Holland, and we should know no more of him until the war was over, and after that I had for some time the pleasure of forgetting his existence. Unfortunately, however, I had overlooked Stephen.

Stephen and I were talking of the war (and incidentally having dinner together) when he told me that a man he knew had told him of a strange coincidence of which his nephew had told him. A friend of his who was at the Front had been in the habit of dining at a certain restaurant where a German waiter——

"Karl," I said.

"You've heard about it?" he asked.

"Only yesterday," I said, "I met a friend who knew someone who was present at the inquest."

"The inquest!"

"Yes," I said. "He shot himself through the heart with one of the seven hundred and twenty-five rifles which were found in her dress-basket."

I didn't allow him to interrupt me.

"He had only recently become engaged to her, I believe. She had been a trusted nurse and governess in many English families for many years, etc., etc. Some day I will tell you all about her. It's a long, long story and rather depressing. But about Karl. His mind had undoubtedly become unhinged and, after escaping from Holland, he found his way to the house where she was employed, learnt that she had been arrested (you see, the red stitches on her handkerchief, which everyone had supposed were laundry marks, turned out to be plans of Hampton Court Maze and the most direct route to Swan and Selfinsons), and, seizing the rifle, he rushed from the house (it was the night the Russians passed through Aberdeen and Upper Norwood) and——"

Stephen apologised to me.

"Karl shall be no more," he said. "Karl the ubiquitous is dead."

"Evening papers please copy," I added.
