黑彼得（19）

“I don't know what to say, Mr. Holmes,” he blurted out at last, with a very red face. “It seems to me that I have been making a fool of myself from the beginning. I understand now, what I should never have forgotten, that I am the pupil and you are the master. Even now I see what you have done, but I don't know how you did it, or what it signifies.”

“Well, well,” said Holmes, good-humouredly. “We all learn by experience, and your lesson this time is that you should never lose sight of the alternative. You were so absorbed in young Neligan that you could not spare a thought to Patrick Cairns, the true murderer of Peter Carey.”

The hoarse voice of the seaman broke in on our conversation.

“See here, mister,” said he, “I make no complaint of being man-handled in this fashion, but I would have you call things by their right names. You say I murdered Peter Carey; I say I killed Peter Carey, and there's all the difference. Maybe you don't believe what I say. Maybe you think I am just slinging you a yarn.”

“Not at all,” said Holmes. “Let us hear what you have to say.”

“It's soon told, and, by the Lord, every word of it is truth. I knew Black Peter, and when he pulled out his knife I whipped a harpoon through him sharp, for I knew that it was him or me. That's how he died. You can call it murder. Anyhow, I'd as soon die with a rope round my neck as with Black Peter's knife in my heart.”

“How came you there?” asked Holmes.

“I'll tell it you from the beginning. Just sit me up a little so as I can speak easy. It was in '83 that it happened—August of that year. Peter Carey was master of the Sea Unicorn, and I was spare harpooner. We were coming out of the ice-pack on our way home, with head winds and a week's southerly gale, when we picked up a little craft that had been blown north. There was one man on her—a landsman. The crew had thought she would founder, and had made for the Norwegian coast in the dinghy. I guess they were all drowned. Well, we took him on board, this man, and he and the skipper had some long talks in the cabin. All the baggage we took off with him was one tin box. So far as I know, the man's name was never mentioned, and on the second night he disappeared as if he had never been. It was given out that he had either thrown himself overboard or fallen overboard in the heavy weather that we were having. Only one man knew what had happened to him, and that was me, for with my own eyes I saw the skipper tip up his heels and put him over the rail in the middle watch of a dark night, two days before we sighted the Shetland lights.

他红着脸，还未想好就说：“福尔摩斯先生，我不知道说什么。好象从一开头我就愚弄了自己。现在我懂得了我永远不该忘记我是学生您是老师。虽然我刚才亲眼看见了你所做的一切，可是我还不明白你是怎样办理的以及它的意义。”

福尔摩斯高兴地说：“好。经一事长一智。这次你的教训是破案的方法不能死守一种。你的注意力全部贯注在年轻的乃尔根身上，分不出一点儿给帕特里克·凯恩兹这个真正谋杀彼得·加里的人。”

这个海员嘶哑的声音打断了我们的谈话。

他说：“先生，您听，这样对待我，我并不抱怨，但是我希望你们说话要确切。你们说我谋杀了彼得·加里，我说我杀了彼得·加里，这个区别很大。也许你们不相信我说的话。也许你们想我在给你们编故事。”

福尔摩斯说：“不是这样的。让我们听听你要说什么。”

“很快就会说完，而且每句话全是真的，我敢向上帝发誓。我很了解黑彼得，当他一抽一出刀子的时候，我知道不是我死就是他死，所以我抄起鱼叉对准他戳去。他就是这样死的。你们说是谋杀。不管怎么说，黑彼得的刀插在我的心脏上，或是绞索套在我的脖子上，我全是一样要死的。”

福尔摩斯问：“你怎么到这儿来的？”

“我对你从头说起。让我坐坐，这样讲话方便些。事情发生在一八八三年——那年的八月。彼得·加里是'海上独角兽'号的船长，我是后备叉鱼手。我们正离开北冰洋的大块碎冰往回行驶，是顶风航行。我们从海上救起一只被吹到北方来的小船，因为刮了一星期的猛烈的南风。船上只有一个人，是一个新水手。我们船上的水手们以为大船已经沉没在海底，这个人乘这只小船去挪威海岸。我猜船上其他海员全死了。一句话，我们把这个人救到我们船上，他和我们的头儿在舱里谈了很长时间。随着这个人打捞上来的行李只有一只铁箱子。这个人的名字从来没有人提到过，至少我是不知道，而且第二天夜晚他就不见了，好象他没有来过船上一样。传出话来说，这个人不是自己跳海便是当时的坏天气把他卷到海里去了。只有一个人知道他出了什么事，就是我，因为我亲眼看见，在深夜第二班的时候，船长把他的两只脚捆住，扔到船栏杆外边。又走了两天我们便看见瑟特兰灯塔了。"
