The air was so pleasant, and the sun was so bright, that he determined on proceeding to his destination on foot. He was hardly out of sight of his own offices when he was overtaken by a friend, who was also walking in the direction of Whitehall. This gentleman was a person of considerable worldly wisdom and experience; he had been officially associated with cases of striking and notorious crime, in which Government had lent its assistance to discover and punish the criminals. The opinion of a person in this position might be of the greatest value to Mr. Troy, whose practice as a solicitor had thus far never brought him into collision with thieves and mysteries. He accordingly decided, in Isabel's interests, on confiding to his friend the nature of his errand to the police. Concealing the name, but concealing nothing else, he described what had happened on the previous day at Lady Lydiard's house, and then put the question plainly to his companion.
"What would you do in my place?"
"In your place," his friend answered quietly, "I should not waste time and money in consulting the police."
"Not consult the police!" exclaimed Mr. Troy in amazement. "Surely, I have not made myself understood? I am going to the Head Office; and I have got a letter of introduction to the chief inspector in the detective department. I am afraid I omitted to mention that?"
"It doesn't make any difference," proceeded the other, as coolly as ever. "You have asked for my advice, and I give you my advice. Tear up your letter of introduction, and don't stir a step further in the direction of Whitehall."
Mr. Troy began to understand. "You don't believe in the detective police?" he said.
"Who
"Who is he?" asked Mr. Troy.
"An old rogue, who was once in your branch of the legal profession," the friend answered. "You may, perhaps, remember the name: they call him 'Old Sharon.'"
"What! The scoundrel who was struck off the Roll of Attorneys, years since? Is he still alive?"
"Alive and prospering. He lives in a court or lane running out of Long Acre, and he offers advice to persons interested in recovering missing objects of any sort. Whether you have lost your wife, or lost your cigar-case, Old Sharon is equally useful to you. He has an inbred capacity for reading the riddle the right way in cases of mystery, great or small. In short, he possesses exactly that analytical faculty to which I alluded just now. I have his address at my office, if you think it worth while to try him."
"Who can trust such a man?" Mr. Troy objected. "He would be sure to deceive me."
