I waited until midnight, but there was no sign of his return, so I retired to my room.
我一直等到半夜，还是没见他回来，我就回房休息去了。
It was no uncommon thing for him to be away for days and nights on end when he was hot upon a scent, so that his lateness caused me no surprise.
他连续几天几夜外出跟踪紧追一个线索是常有的事，因而他今天迟迟不归并不使我奇怪。
I do not know at what hour he came in,
我不知道他是什么时候回来的，
but when I came down to breakfast in the morning there he was with a cup of coffee in one hand and the paper in the other, as fresh and trim as possible.
但是当我早晨下楼进早餐时，只见他已经坐在那里了，一只手端着一杯咖啡，另一只手拿着一份报纸，精神饱满，雍容整洁。
"You will excuse my beginning without you, Watson," said he, "but you remember that our client has rather an early appointment this morning."
"对不起，华生，我没等你便先吃起来了。"他说，"但是你不要忘记我们的委托人今天上午和我们的约会。"
"Why, it is after nine now," I answered. "I should not be surprised if that were he. I thought I heard a ring."
"怎么，现在已过九点钟了，"我回答说，"我想一定是他在叫门。我听到了门铃响。"

It was, indeed, our friend the financier.
果然，来的正是我们这位金融家朋友。
I was shocked by the change which had come over him, for his face which was naturally of a broad and massive mould,
他身上发生的变化，使我感到非常震惊，因为他天生又宽阔又结实的脸庞，
was now pinched and fallen in, while his hair seemed to me at least a shade whiter.
现在消瘦并瘪了下去，他的头发好象也比以前更灰白了。
He entered with a weariness and lethargy which was even more painful than his violence of the morning before,
他带着萎靡困顿的倦容走了进来，显得比前一天早晨那种狂暴的样子更加痛苦，
and he dropped heavily into the armchair which I pushed forward for him.
他沉重地跌坐在我推给他的扶手椅上。
