海军协定（5）（在线收听）

“You come at a crisis, Watson,” said he. “If this paper remains blue, all is well. If it turns red, it means a man's life.” He dipped it into the test-tube and it flushed at once into a dull, dirty crimson. “Hum! I thought as much!” he cried. “I will be at your service in an instant, Watson. You will find tobacco in the Persian slipper.” He turned to his desk and scribbled off several telegrams, which were handed over to the page-boy. Then he threw himself down into the chair opposite, and drew up his knees until his fingers clasped round his long, thin shins.

“A very commonplace little murder,” said he. “You've got something better, I fancy. You are the stormy petrel of crime, Watson. What is it?”

I handed him the letter, which he read with the most concentrated attention.

“It does not tell us very much, does it?” he remarked, as he handed it back to me.

“Hardly anything.”

“And yet the writing is of interest.”

“But the writing is not his own.”

“Precisely. It is a woman's.”

“A man's surely,” I cried.

“No, a woman's, and a woman of rare character. You see, at the commencement of an investigation it is something to know that your client is in close contact with some one who, for good or evil, has an exceptional nature. My interest is already awakened in the case. If you are ready we will start at once for Woking, and see this diplomatist who is in such evil case, and the lady to whom he dictates his letters.”

“你来得正是时候，华生，”福尔摩斯说道，“如果这张纸仍然呈蓝色，就一切正常。如果它变成了红色，那溶液就能致人于死地。”他把纸浸入试管，立即变成了深暗而污浊的红色。“嘿！丙然不出我所料！”他高喊道，“华生，我马上就可以听你吩咐了。你可以在波斯拖鞋里拿到烟叶。”他转身走向书桌，潦草地写了几份电报，把它们一交一给了小听差，然后坐到我对面的椅子上，曲起双膝，双手紧抱住瘦长的小腿。

“一件平淡无奇的凶杀案，”福尔摩斯说道，“我想，你给我带来的案子会有趣得多。华生，你是没有麻烦事不来的，出了什么事呢？”

我把信递给他，他全神贯注地读起来。

“这信没有向我们说明多少情况，对不对？”福尔摩斯把信一交一还给我时说道。

“几乎没说明什么。”我说道。

“不过笔迹倒很值得注意呢。”

“不过这笔迹不是他的。”

“确实如此，那是女人写的。”

“一定是男人写的，”我大声说道。

“不，是女人写的，而且是一个具有不平常一性一格的女人。

你看，重要的是，从调查一开始，我们就知道，你的委托人和一个人有密切关系，那个人，无论从哪方面看，都具有与众不同的一性一格。这件案子现在已经使我发生了兴趣。如果你乐意的话，我们可以马上动身前往沃金，去看看那位遭遇此种不幸的外一交一官，和照他的口述代写这封信的女人。”
