I was on safer ground when I came to the questions of the likeness. There were points of difference between the two. This man looked a little shorter and thinner; smaller altogether; too old for Twickenham. Twickenham was only forty-six; his double looked sixty. Then he had a scar on his right cheek, which Twickenham had never had. Still these things, I had perforce to admit, were quite reconcilable with the fact that the man was Twickenham. What alterations might not have taken place in such a fifteen years! The exhibition was not liberally patronised. There had been two or three other spectators when I came in, but they had gone, and no others had taken their place. The duration of my visit, and the unmistakable interest which I took in the figure on the mattress, probably, also, the peculiar quality of my interest, attracted the attention of the individual in charge. This was the gentleman who had requested me not to lean against the glass case. He was a short, slight person, with red hair and moustache. He wore a frock coat and a hat which had seen better days, and had a trick of stroking his moustache with one of the dirtiest right hands I had ever seen; which, however, matched the voluminous shirt-cuff which protruded from the sleeve of his coat. I was conscious that for some seconds he had been eyeing me askance. Now he came sidling up--his dirty hand on his moustache. 'Wonderful man, sir.' He alluded to the figure on the mattress. 'I suppose he really is asleep?' 'What do you think he is--dead?' 'He looks to me as if he were dead.' 'That's not surprising, considering that for eight-and-twenty days he's tasted neither bite nor sup.' 'Is that really the case?' 'Certainly. He hasn't had so much as a drop of water. The case is locked; the key is in possession of the manager of the Aquarium. Doctors are constantly in and out to see there's no collusion. You'll find their reports outside. It's will-power does it. He wills that he shall go to sleep for thirty days, and he goes to sleep for thirty days. To try to wake him up before the end of the thirty days, to give him, say, a glass of water, would probably cause his death.' 'That's very curious.' 'It's more than curious; it's the greatest marvel of the age.' 'And when does he wake?' 'At ten o'clock on Saturday evening next--in the presence of the manager and staff of the Aquarium, and a large representative body of distinguished medical gentlemen. It will be the sensation of the hour. Though we shall charge double prices for admission, the room won't hold the people.' I wondered. At present there seemed a good deal of space to spare. 'What is his name?' 'Montagu Babbacombe--a name known all over the world.' The little man eyed me sharply. 'I meant, what is his real name?' 'His real name? What do you mean? That is his real name.' 'How long have you known him?' 'May I ask, sir, what prompts you to put that inquiry to me?'
