“You think a man must be well-to-do if he smokes a seven-shilling pipe?” said I.

“This is Grosvenor mixture at eightpence an ounce,” Holmes answered, knocking a little out on his palm. “As he might get an excellent smoke for half the price, he has no need to practise economy.”

“And the other points?”

“He has been in the habit of lighting his pipe at lamps and gas jets. You can see that it is quite charred all down one side. Of course a match could not have done that. Why should a man hold a match to the side of his pipe? But you cannot light it at a lamp without getting the bowl charred. And it is all on the right side of the pipe. From that I gather that he is a left-handed man. You hold your own pipe to the lamp and see how naturally you, being right-handed, hold the left side to the flame. You might do it once the other way, but not as a constancy. This has always been held so. Then he has bitten through his amber. It takes a muscular, energetic fellow, and one with a good set of teeth, to do that. But if I am not mistaken I hear him upon the stair, so we shall have something more interesting than his pipe to study.”

An instant later our door opened, and a tall young man entered the room. He was well but quietly dressed in a dark gray suit and carried a brown wide-awake in his hand. I should have put him at about thirty, though he was really some years older.

“你认为他用一只七先令的烟斗吸烟，那就是一个有钱的人吗？”我问道。

“这是格罗夫纳板烟，八便士一英两，”福尔摩斯说着，把烟斗在手心中磕出一点烟丝来，”用这一半的价钱，他就可以抽上等烟了，可见他是经济富裕的了。”

“那么，别的几点呢？”

“他有在油灯和煤气喷灯上点烟斗的习惯。你可以看出这烟斗的一边已经烧焦了。当然用火柴就不会弄成这样了。用火柴点烟怎么会烧焦烟斗边呢？但你在油灯上把烟点着，就不能不烧焦烟斗。而烧焦的只是烟斗的右侧，由此，我推测他是一个使用左手的人。现在你把你的烟斗在灯上点燃，你就可以看到，因为你惯用右手，自然是左边侧向火焰了。有时你也许不这么点烟，但这毕竟不是经常的。所以只能认为他惯用左手。琥珀嘴已被咬穿，说明他身强力壮，牙齿整齐。如果我没有弄错的话，我听到他已走上楼来，那么，我们就可以研究一些比这烟斗更有趣的问题了。”

过了一会儿，我们的屋门开了，一个身材高大的年轻人走进来。他身穿一套讲究而素净的深灰色衣服，手中拿着一顶褐色宽檐呢帽。我猜他的年龄在三十岁上下，可是实际上他还要大几岁。
