I had come to these conclusions before ever I had entered his room.
我在走进他的房间之前就已得出了这个结论。
An inspection of his chair showed me that he had been in the habit of standing on it,
对他椅子的检查证明，他常常站在椅子上，
which of course would be necessary in order that he should reach the ventilator.
为了够得着通气孔这当然是必要的。
The sight of the safe, the saucer of milk, and the loop of whipcord
见到保险柜，那一碟牛奶和鞭绳的活结

就足以消除余下的任何怀疑了。
The metallic clang heard by Miss Stoner was obviously caused by her stepfather hastily closing the door of his safe upon its terrible occupant.

"结果把它从通气孔赶了回去。"

"结果还引起它在另一头反过去扑向它的主人。

我那几下藤鞭子抽打得它够受的，激起了它的毒蛇本性，因而它就对第一个见到的人狠狠地咬了一口。
In this way I am no doubt indirectly responsible for Dr. Grimesby Roylott's death,
这样，我无疑得对格里姆斯比·罗伊洛特医生的死间接地负责。
and I cannot say that it is likely to weigh very heavily upon my conscience."
凭良心说，我是不大会为此而感到内疚的。"
