“Lord! you don’t look it—nothing like it,” he cried boyishly.

Nor did she. She carried a graceful air of youth, from the wave of brown hair that escaped from beneath her Sister’s cap to the supple and delicately curved figure. And her face, if you peered not too closely, was young, very pure in feature, still with a bloom on the complexion in spite of confinement in hospital wards. Her voice, too, was soft and youthful. Perhaps her eyes were a little weary—they had seen many terrible things.

At the young man’s tribute she flushed slightly and smiled. But the smile died away when he added:

“What was he like? I’ve often wondered, and there has been no one to tell me—no one I could have listened to. The dons of his generation are too shy to refer to him and I’m too shy to ask ’em. Do you know, I’ve never seen a picture of him even.”

“He was not unlike you,” she replied, looking not at him, but wistfully down the years. “Of heavier build. He was a man of tremendous vitality—and swift brain. The most marvellous teacher I have ever met. He seemed to hold your intellect in his hands like a physical thing, sweep it clear of cobwebs and compel it to assimilate whatever he chose. A born teacher and a wonderful man.”

“But was he human? I know his work, though I haven’t read enough to tackle it yet—most of it’s away and beyond Part II of the Tripos even. I went up with an Open Mathematical Scholarship just before the war, and only did my first year’s reading. I’m beginning this”—he tapped his Treatise on Rigid Dynamics—“on my own. What I mean is,” he went on, after a pause, “my father has been always an abstraction to me. I shouldn’t have worried about him if he had just been a nonentity—it wasn’t playing the game to vanish as he did into space and leave my mother to fend for herself.”

“But I heard,” said the Sister, “that your mother had her own private fortune.”

“I wasn’t alluding to that side of it,” he admitted. “But he did vanish, didn’t he? Well, as I say, if he had been just a nobody, I shouldn’t have been particularly interested; but he wasn’t. He was the most brilliant man of his generation at Cambridge. For instance, he took up Chinese as a sort of relaxation. They say his is the only really scientific handbook on the study of the language. You see, Sister”—he swerved impatiently on his chair and brought his hand down on the table, whereat she drew a swift inward breath, for the gesture of the son was that of the father—“I’ve always wanted to know whether I’m the son of an inhuman intellect or of a man of flesh and blood. Was he human? That’s what I want to know.”

“He was human all right,” she replied quietly. “Too human. Of course he was essentially the scholar—or savant—whatever you like to call it. His work was always to him an intellectual orgy. But he loved the world too. He was a fascinating companion. He seemed to want to get everything possible out of life.”

“Why didn’t he get it?”
