THE next day, Mr. Troy (taking Robert Moody with him as a valuable witness) rang the bell at the mean and dirty lodging-house in which Old Sharon received the clients who stood in need of his advice.

They were led up stairs to a back room on the second floor of the house. Entering the room, they discovered through a thick cloud of tobacco smoke, a small, fat, bald-headed, dirty, old man, in an arm-chair, robed in a tattered flannel dressing-gown, with a short pipe in his mouth, a pug-dog on his lap, and a French novel in his hands.

“Is it business?” asked Old Sharon, speaking in a hoarse, asthmatical voice, and fixing a pair of bright, shameless, black eyes attentively on the two visitors.

“It is business,” Mr. Troy answered, looking at the old rogue who had disgraced an honorable profession, as he might have looked at a reptile which had just risen rampant at his feet. “What is your fee for a consultation?”

“You give me a guinea, and I’ll give you half an hour.” With this reply Old Sharon held out his unwashed hand across the rickety ink-splashed table at which he was sitting.

Mr. Troy would not have touched him with the tips of his own fingers for a thousand pounds. He laid the guinea on the table.

Old Sharon burst into a fierce laugh — a laugh strangely accompanied by a frowning contraction of his eyebrows, and a frightful exhibition of the whole inside of his mouth. “I’m not clean enough for you — eh?” he said, with an appearance of being very much amused. “There’s a dirty old man described in this book that is a little like me.” He held up his French novel. “Have you read it? A capital story — well put together. Ah, you haven’t read it? You have got a pleasure to come. I say, do you mind tobacco-smoke? I think faster while I smoke — that’s all.”

Mr. Troy’s respectable hand waved a silent permission to smoke, given under dignified protest.

“All right,” said Old Sharon. “Now, get on.”

He laid himself back in his chair, and puffed out his smoke, with eyes lazily half closed, like the eyes of the pug-dog on his lap. At that moment, indeed there was a curious resemblance between the two. They both seemed to be preparing themselves, in the same idle way, for the same comfortable nap.

Mr. Troy stated the circumstances under which the five hundred pound note had disappeared, in clear and consecutive narrative. When he had done, Old Sharon suddenly opened his eyes. The pug-dog suddenly opened his eyes. Old Sharon looked hard at Mr. Troy. The pug looked hard at Mr. Troy. Old Sharon spoke. The pug growled.

“I know who you are — you’re a lawyer. Don’t be alarmed! I never saw you before; and I don’t know your name. What I do know is a lawyer’s statement of facts when I hear it. Who’s this?” Old Sharon looked inquisitively at Moody as he put the question.

Mr. Troy introduced Moody as a competent witness, thoroughly acquainted with the circumstances, and ready and willing to answer any questions relating to them. Old Sharon waited a little, smoking hard and thinking hard. “Now, then!” he burst out in his fiercely sudden way. “I’m going to get to the root of the matter.”

He leaned forward with his elbows on the table, and began his examination of Moody. Heartily as Mr. Troy despised and disliked the old rogue, he listened with astonishment and admiration — literally extorted from him by the marvelous ability with which the questions were adapted to the end in view. In a quarter of an hour Old Sharon had extracted from the witness everything, literally everything down to the smallest detail, that Moody could tell him. Having now, in his own phrase, “got to the root of the matter,” he relighted his pipe with a grunt of satisfaction, and laid himself back in his old armchair.

“Well?” said Mr. Troy. “Have you formed your opinion?”

“Yes; I’ve formed my opinion.”

“What is it?”

Instead of replying, Old Sharon winked confidentially at Mr. Troy, and put a question on his side.

“I say! is a ten-pound note much of an object to you?”

“It depends on what the money is wanted for,” answered Mr. Troy.

“Look here,” said Old Sharon; “I give you an opinion for your guinea; but, mind this, it’s an opinion founded on hearsay — and you know as a lawyer what that is worth. Venture your ten pounds — in plain English, pay me for my time and trouble in a baffling and difficult case — and I’ll give you an opinion founded on my own experience.”

“Explain yourself a little more clearly,” said Mr. Troy. “What do you guarantee to tell us if we venture the ten pounds?”

“I guarantee to name the person, or the persons, on whom the suspicion really rests. And if you employ me after that, I guarantee (before you pay me a halfpenny more) to prove that I am right by laying my hand on the thief.”

“Let us have the guinea opinion first,” said Mr. Troy.

Old Sharon made another frightful exhibition of the whole inside of his mouth; his laugh was louder and fiercer than ever. “I like you!” he said to Mr. Troy, “you are so devilish fond of your money. Lord! how rich you must be! Now listen. Here’s the guinea opinion: Suspect, in this case, the very last person on whom suspicion could possibly fall.”

Moody, listening attentively, started, and changed color at those last words. Mr. Troy looked thoroughly disappointed and made no attempt to conceal it.

“Is that all?” he asked.

“All?” retorted the cynical vagabond. “You’re a pretty lawyer! What more can I say, when I don’t know for certain whether the witness who has given me my information has misled me or not? Have I spoken to the girl and formed my own opinion? No! Have I been introduced among the servants (as errand-boy, or to clean the boots and shoes, or what not), and have I formed my own judgement of them? No! I take your opinions for granted, and I tell you how I should set to work myself if they were my opinions too — and that’s a guinea’s-worth, a devilish good guinea’s-worth to a rich man like you!”

Old Sharon’s logic produced a certain effect on Mr. Troy, in spite of himself. It was smartly put from his point of view — there was no denying that.

“Even if I consented to your proposal,” he said, “I should object to your annoying the young lady with impertinent questions, or to your being introduced as a spy into a respectable house.”

Old Sharon doubled his dirty fists and drummed with them on the rickety table in a comical frenzy of impatience while Mr. Troy was speaking.

“What the devil do you know about my way of doing my business?” he burst out when the lawyer had done. “One of us two is talking like a born idiot — and (mind this) it isn’t me. Look here! Your young lady goes out for a walk, and she meets with a dirty, shabby old beggar — I look like a shabby old beggar already, don’t I? Very good. This dirty old wretch whines and whimpers and tells a long story, and gets sixpence out of the girl — and knows her by that time, inside and out, as well as if he had made her —............
