"Wandering round, living on three pounds a week, partly amusing myself, partly collecting material for a few little articles. 'What it Feels Like to be a Conquered Nation'—sob-stuff for the Liberal press, you know—and 'How the Hun is Trying to Wriggle out of the Indemnity,' for the other fellows. One has to make the best of all possible worlds, don't you find? But we mustn't talk shop. Well, I was wandering round, and very pleasant I found it. Berlin, Dresden, Leipzig. Then down to Munich and all over the place. One fine day I got to Grauburg. You know Grauburg? It's one of those picture-book German towns with a castle on a hill, hanging beer-gardens, a Gothic church, an old university, a river, a pretty bridge, and forests all round. Charming. But I hadn't much opportunity to appreciate the beauties of the place. The day after I arrived there—bang!—I went down with appendicitis—screaming, I may add."

"But how appalling!"

"They whisked me off to hospital, and cut me open before you could say knife. Excellent surgeon, highly efficient Sisters of Charity to nurse me—I couldn't have been in better hands. But it was a bore being tied there by the leg for four weeks—a great bore. Still, the thing had its compensations. There was my nun, for example. Ah, here's the food, thank Heaven!"

The mixed grill proved to be excellent. Miss Penny's description of the pun came to me in scraps and snatches. A round, pink, pretty face in a winged coif; blue eyes and regular features; teeth altogether too perfect—false, in fact; but the general effect extremely pleasing. A youthful Teutonic twenty eight.

"She wasn't my nurse," Miss Penny explained. "But I used to see her quite often when she came in to have a look at the tolle Engländerin. Her name was Sister Agatha. During the war, they told me, she had converted any number of wounded soldiers to the true faith—which wasn't surprising, considering how pretty she was."

"Did she try and convert you?" I asked.

"She wasn't such a fool." Miss Penny laughed, and rattled the miniature gallows of her ears.

I amused myself for a moment with the thought of Miss Penny's conversion—Miss Penny confronting a vast assembly of Fathers of the Church, rattling her earrings at their discourses on the Trinity, laughing her appalling laugh at the doctrine of the Immaculate Conception, meeting the stern look of the Grand Inquisitor with a flash of her bright, emotionless hare's eyes. What was the secret of the woman's formidableness?

But I was missing the story. What had happened? Ah yes, the gist of it was that Sister Agatha had appeared one morning, after two or three days absence, dressed, not as a nun, but in the overalls of a hospital charwoman, with a handkerchief instead of a winged coif on her shaven head.

"Dead," said Miss Penny; "she looked as though she were dead. A walking corpse, that's what she was. It was a shocking sight. I shouldn't have thought it possible for anyone to change so much in so short a time. She walked painfully, as though she had been ill for months, and she had great burnt rings round her eyes and deep lines in her face. And the general expression of unhappiness—that was something quite appalling."
