'If Dr Jekyll has been murdered, why is his murderer still there? What reason could he possibly have for staying?'
“如果杰基尔博士给人害了，为什么凶手还在这儿？是什么原因让他留在这里呢？”

'Perhaps you don't believe me, sir, but I know what I heard. For a week now the person, or thing, in that study has been crying night and day for some special chemical powders. My master was in the habit, when he was particularly busy with his scientific work, of writing orders on pieces of paper and leaving them on the stairs. 'We've had nothing else this week, nothing except written orders and a locked door. I've been to every chemist in town in search of these chemicals of his, but they were never right. They weren't pure enough, he said. I had to take them back to the shop, and try another chemist. I don't know what these chemicals are, but the person in that study wants them terribly badly.'
“好吧，先生，也许您不信我的话，但我明白我听见了什么。快一个星期了，那个人，也许是什么怪物，在书房里没日没夜地哭，要一种特别的药粉。主人每次一忙，就是这样，把命令写在纸条上，扔在楼梯上，这倒是他一贯的作风。这次也是，我们别的什么也不知道，只有吩咐的纸条和关紧的门。我去过城里所有的药店，找他要的东西，可没一样符合他的要求。他说那些玩意不纯，我又得把东西退回去，再上别的店。我不知道这些药是干什么的，可书房里的那个人要得那么急。”
