THE intelligence with which Lestrade greeted us was so momentous and so unexpected that we were all three fairly dumfounded.

雷斯垂德给我们带来的消息既重要又突然，完全出乎意料之外。我们听了以后，全都惊愕不已，哑口无言。

" What's this" ? he said, stopping on the threshold, taken aback, dumfounded.

“这是什么” ？他说，停在门槛上， 大吃一惊，目瞪口呆。

Then the two old gentlemen shouted with laughter, but I was dumfounded, just petrified, as you may say.

然后两位老先生大笑起来， 但我却傻眼了， 你可能会说， 我简直惊呆了。
