“His soul swayed in a vertigo of moral indecision. He had only to snap the thread of a rash vow made to a villainous society, and all his life could be as open and sunny as the square beneath him. He had, on the other other hand, only to keep his antiquated honour, and be delivered inch by inch into the power of this great enemy of mankind, whose very intellect was a torture-chamber. Whenever he looked down into the square he saw the comfortable policeman, a pillar of common sense and common order. Whenever he looked back at the breakfast-table he saw the President still quietly studying him with big, unbearable eyes.”

“He had thought at first that they were all of common stature and costume, with the evident exception of the hairy Gogol. But as he looked at the others, he began to see in each of them exactly what he had seen in the man by the river, a demoniac detail somewhere. That lop-sided laugh, which would suddenly disfigure the fine face of his original guide, was typical of all these types. Each man had something about him, perceived perhaps at the tenth or twentieth glance, which was not normal, and which seemed hardly human. The only metaphor he could think of was this, that they all looked as men of fashion and presence would look, with the additional twist given in a false and curved mirror.”

“It was like the face of some ancient archangel, judging justly after heroic wars. There was laughter in the eyes, and in the mouth honour and sorrow. There was the same white hair, the same great, grey-clad shoulders that I had seen from behind. But when I saw him from behind I was certain he was an animal, and when I saw him in front I knew he was a god.”

“He felt the full warmth of that pleasure from which the proud shut themselves out; the pleasure which not only goes with humiliation, but which almost is humiliation. Men who have escaped death by a hair have it, and men whose love is returned by a woman unexpectedly, and men whose sins are forgiven them. Everything his eye fell on it feasted on, not aesthetically, but with a plain, jolly appetite as of a boy eating buns. He relished the squareness of the houses; he liked their clean angles as if he had just cut them with a knife. The lit squares of the shop windows excited him as the young are excited by the lit stage of some promising pantomime. He happened to see in one shop which projected with a bulging bravery on to the pavement some square tins of potted meat, and it seemed like a hint of a hundred hilarious high teas in a hundred streets of the world. He was, perhaps, the happiest of all the children of men. For in that unendurable instant when he hung, half slipping, to the ball of St. Paul's, the whole universe had been destroyed and re-created.”

“Being surrounded with every conceivable kind of revolt from infancy, Gabriel had to revolt into something, so he revolted into the only thing left — sanity. But there was just enough in him of the blood of these fanatics to make even his protest for common sense a little too fierce to be sensible.”

“He thought his detective brain as good as the criminal's, which was true. But he fully realised the disadvantage. "The criminal is the creative artist; the detective only the critic," he said with a sour smile, and lifted his coffee cup to his lips slowly, and put it down very quickly. He had put salt in it.”

“He stared and talked at the girl's red hair and amused face for what seemed to be a few minutes; and then, feeling that the groups in such a place should mix, rose to his feet. To his astonishment, he discovered the whole garden empty. Everyone had gone long ago, and he went himself with a rather hurried apology. He left with a sense of champagne in his head, which he could not afterwards explain. In the wild events which were to follow, this girl had no part at all; he never saw her again until all his tale was over. And yet, in some indescribable way, she kept recurring like a motive in music through all his mad adventures afterwards, and the glory of her strange hair ran like a red thread through those dark and ill-drawn tapestries of the night. For what followed was so improbable that it might well have been a dream.”
