On a Sunday of his honeymoon in London he had conceived with Mabel the idea of a bus ride through the streets,--"anywhere, the first bus that comes." The first bus that came took them through South London, dodged between main roads and took them through miles of mean and sordid dwelling houses. At open windows high up sat solitary women, at others solitary, shirt-sleeved men; behind closed windows were the faces of children. All staring,--women and men and children, impassively prisoned, impassively staring. Each house door presented, one above the other, five or six iron bell-knobs, some hanging out and downwards, as if their necks were broken. On the pavements hardly a soul. Just street upon street of these awful houses with their imprisoned occupants and the doors with their string of crazy bells. An appalling and abysmal depression settled upon Sabre. He imagined himself pulling the dislocated neck of one of those bells and stepping into what festered behind those sinister doors: the dark and malodorous stairways, the dark and malodorous rooms, their prisoned occupants opening their prisons and staring at him,--those women, those men, those children. He imagined himself in one of those rooms, saw it, felt it, smelt it. He imagined himself cutting his throat in one of those rooms. At tea in their hotel on their return Mabel chattered animatedly on all they had seen. "I'm awfully glad we went. I think it's a very good thing to know for oneself just how that side of life lives. Those awful people at the windows!"--and she laughed. He noticed for the first time what a sudden laugh she had, rather loud. Sabre agreed. "Yes, I think it's a good thing to have an idea of their lives. I can't say I'm glad I went, though. You've no idea how awfully depressed that kind of thing makes me feel." She laughed again. "Depressed! How ever can it? How funny you must be!" Then she said, "Yes, I'm glad I've seen for myself. You know, when those sort of people come into your service--the airs they give themselves and the way they demand the best of everything--and then when you see the kind of homes they come from--!" "Yes, it makes you think, doesn't it?" "It _does_!" But what it made Sabre think was entirely different from what it made Mabel think. VII "Puzzlehead" they had called him at his preparatory school,--Old Puzzlehead Sabre, the chap who always wrinkled up his nut over things and came out with the most extraordinary ideas. He had remained, and increasingly become, the puzzler. And precisely as he ceased to share a room with Mabel and carried himself with satisfaction to his own apartment, so, by this fifth year of his married life, he had come to know well that he shared no thoughts with her: he carried them, with increasing absorption in their interest, to the processes of his own mind.
