[00:00.06]Chapter four. [00:02.13]A rat. [00:04.84]After lunch, Holmes sat with his tapering fingers together, staring into space. [00:11.87]Then he turned to me. [00:14.46]I don't know quite what to do, Watson. [00:18.69]I should value your advice. [00:21.58]Let me explain. [00:25.92]Pray do so. [00:29.52]Let us presume that what young James said was true. [00:34.94]In what respect? [00:39.70]About two things in particular. [00:44.41]One, I mentioned earlier, that his father called "Cooe" before seeing him. [00:53.70]The other was McCarthy's dying words about a rat. [01:00.87]What of this "Cooe" then? [01:04.44]It could not have been meant for his son. [01:08.71]As far as McCarthy knew, his son was in Bristol. [01:14.71]The Cooe was meant to call the person he was meeting. [01:20.76]But Cooe is an Australian greeting. [01:26.75]Hence, he was expecting to meet someone from Australia. [01:35.05]I nodded. [01:37.34]And the rat? [01:41.56]Holmes took out a folded paper from his pocket. [01:46.76]This is a map of the colony of Victoria in Australia. [01:54.13]I had it sent over this morning. [01:58.89]He put his hand over part of the map. [02:03.12]What do you read? [02:06.25]Arat, I said. [02:11.40]And now? [02:13.93]He raised his hand. [02:16.87]I could see the whole word. [02:22.39]Ballarat. [02:26.51]Quite so. [02:29.85]That was the word that McCarthy spoke. [02:35.32]His son heard the last part only. [02:39.35]He was trying to say the name of his murderer. [02:46.76]So and so of Ballarat. [02:55.86]That's wonderful. [02:59.09]It's obvious. [03:01.72]Now, you see, I have narrowed down the field. [03:08.32]A tall Australian who is at home in the district. [03:15.74]At home enough to find his way through the back of the estate. [03:23.99]His height you deduced from the length of his stride and his boots. [03:31.60]But what about his lameness? [03:36.92]The mark of his right foot was always less clear than his left. [03:45.54]He put less weight on it. [03:48.77]Why? [03:50.84]Because he limped. [03:57.80]But his left-handedness? [04:02.94]You notice the injury as reported at the inquest. [04:09.72]A blow struck from behind, yet from the left side. [04:18.47]Surely a left-handed man? [04:23.33]He stood behind the tree during the argument between James and his father. [04:31.27]He even smoked there. [04:35.26]I found the ash of a cigar. [04:41.35]As you know, I am an expert on tobacco ash. [04:48.82]I then discovered the cigar stump in the moss where he had thrown it. [04:57.09]And the cigar holder? [05:01.83]The cigar had not been in his mouth. [05:06.33]Therefore, he had used a holder. [05:12.92]The tip had been cut off, not bitten. [05:21.39]It was not a clean cut. [05:25.39]So, I deduced a blunt pen knife. [05:33.27]I see where this all points. [05:37.15]The murderer must be Mr. [05:41.44]John Turner!" cried a voice. [05:45.95]It was the hotel waiter opening the door. [05:50.74]He showed a visitor into the room. [05:57.58]The man who entered was a strange and impressive figure. [06:04.81]He had a slow, limping step, but his craggy face and huge arms and legs gave an impression of strength of body and character. [06:19.06]His face was white and his lips tinged with blue. [06:24.60]As a doctor, I could see that he was a very ill man. [06:33.87]Pray, take a seat," said Holmes. [06:38.56]You got my note?" [06:43.29]The lodgekeeper brought it. [06:46.00]You said you wished to see me here to avoid scandal. [06:52.68]I thought people would talk if I came to the hall. [06:59.63]And why did you wish to see me?" the man asked wearily. [07:07.09]I know all about McCarthy," said Holmes. [07:14.62]The old man sunk his face in his hands. [07:20.46]God help me," he cried. [07:26.45]But I would have spoken out. [07:29.76]I would not have let that young man come to harm. [07:36.12]I am glad to hear it," said Holmes gravely. [07:45.60]I would have spoken of it already, but my dear daughter, it will break her heart when she sees me arrested. [07:58.30]It may not come to that," said Holmes. [08:03.62]What? [08:06.32]I am no police officer. [08:11.90]Your daughter invited me here, and I am acting in her interests. [08:20.13]Young McCarthy must be got off, however. [08:28.65]I am a dying man," said Turner. [08:34.83]The doctor says I have but a month, yet I would sooner die under my own roof than in jail. [08:46.59]Just tell us the truth while I jot down the facts. [08:52.64]You will sign it with Watson as witness. [08:57.22]If the case goes against young McCarthy, I shall use your confession. [09:04.66]You may be assured I shall not use it unless it is absolutely needed. [09:14.58]It's as well," said the old man. [09:19.74]I doubt I shall live until the trial, but I would still like to spare Alice the shock. [09:29.62]I will tell you all. [09:32.89]It will not take long.
