In the spring of 1917, when Doctor Richard Diver first arrived in Zurich, he was twenty-six years old, a fine age for a man, indeed the very acme of bachelorhood. Even in war-time days, it was a fine age for Dick, who was already too valuable, too much of a capital investment to be shot off in a gun. Years later it seemed to him that even in this sanctuary he did not escape lightly, but about that he never fully made up his mind — in 1917 he laughed at the idea, saying apologetically that the war didn’t touch him at all. Instructions from his local board were that he was to complete his studies in Zurich and take a degree as he had planned.

Switzerland was an island, washed on one side by the waves of thunder around Gorizia and on another by the cataracts along the Somme and the Aisne. For once there seemed more intriguing strangers than sick ones in the cantons, but that had to be guessed at — the men who whispered in the little cafés of Berne and Geneva were as likely to be diamond salesmen or commercial travellers. However, no one had missed the long trains of blinded or one-legged men, or dying trunks, that crossed each other between the bright lakes of Constance and Neuchatel. In the beer-halls and shop- windows were bright posters presenting the Swiss defending their frontiers in 1914 — with inspiring ferocity young men and old men glared down from the mountains at phantom French and Germans; the purpose was to assure the Swiss heart that it had shared the contagious glory of those days. As the massacre continued the posters withered away, and no country was more surprised than its sister republic when the United States bungled its way into the war.

Doctor Diver had seen around the edges of the war by that time: he was an Oxford Rhodes Scholar from Connecticut in 1914. He returned home for a final year at Johns Hopkins, and took his degree. In 1916 he managed to get to Vienna under the impression that, if he did not make haste, the great Freud would eventually succumb to an aeroplane bomb. Even then Vienna was old with death but Dick managed to get enough coal and oil to sit in his room in the Damenstiff Strasse and write the pamphlets that he later destroyed, but that, rewritten, were the backbone of the book he published in Zurich in 1920.

Most of us have a favorite, a heroic period, in our lives and that was Dick Diver’s. For one thing he had no idea that he was charming, that the affection he gave and inspired was anything unusual among healthy people. In his last year at New Haven some one referred to him as “lucky Dick”— the name lingered in his head.

“Lucky Dick, you big stiff,” he would whisper to himself, walking around the last sticks of flame in his room. “You hit it, my boy. Nobody knew it was there before you came along.”

At the beginning of 1917, when it was becoming difficult to find coal, Dick burned for fuel almost a hundred textbooks that he had accumulated; but only, as he laid each one on the fire, with an assurance chuckling inside him that he was himself a digest of what was within the book, that he could brief it five years from now, if it deserved to be briefed. This went on at any odd hour, if necessary, with a floor rug over his shoulders, with the fine quiet of the scholar which is nearest of all things to heavenly peace — but which, as will presently be told, had to end.

For its temporary continuance he thanked his body that had done the flying rings at New Haven, and now swam in the winter Danube. With Elkins, second secretary at the Embassy, he shared an apartment, and there were two nice girl visitors — which was that and not too much o............
