"Right again," I exclaimed. "Now you had better wait around there until the hack returns; then get into conversation with the driver, and ask him to take a drink in the nearest saloon; while you are talking with him, you can easily learn where Pattmore went."

It was ten o'clock when Knox left me, and, as I was greatly fatigued, I went to bed immediately. Shortly after midnight, Knox again awoke me.

"What news?" I asked, starting up. "Did you succeed in learning anything from the hackman?"

"Yes," replied Knox; "he returned a little before eleven o'clock, and I asked him whether he knew where there were any young ladies I could visit. He said that he knew several places. I then asked him to take a drink while we talked about it. I said, I judged, from his appearance, that he was just the young fellow who could take me where I wanted to go; that I was crossing the street to employ him in the early part of the evening, when he was taken by another gentleman, who probably went to the same kind of a place that I wanted to find. This had confirmed my opinion of the hackman, so I had decided to await his return. 'By the way,' I added, 'was I right about that gentleman?' The driver laughed loudly, and said that that was Mr. Pattmore, and that he did not go to such places. He went on to say that Mr. Pattmore's wife had been dead only a few days, and he supposed that Mr. Pattmore had gone out to pay the grave-digger, since his visit had been made to that individual at the graveyard gate."

"Did the boy say whether Pattmore saw the grave-digger?" I asked.

"Yes," continued Knox; "I pumped out all that the young fellow knew. The grave-digger lives in a little shanty close by the graveyard, and, on arriving there, Pattmore called the fellow to one side, and conversed with him in a low tone for some time. He then paid him some money, entered the hack, and told the boy to drive straight back to the Pattmore House, where Pattmore discharged the hackman. I drew this information out of the boy very easily, without appearing to take any special interest in the story. I then told him to drive me to some quiet house where I could meet some young ladies. He took me to a place near here, and I paid him off immediately, saying that I should spend the night there. As soon as he was out of sight, I came straight here, without going into the house at all."

"By Jove!" I exclaimed, "we shall have some rough work to-night, and we must be quick, too. Go over to the Pattmore House, find out from the register what room Green is in, and wake him up as soon as possible. Tell him to come here, being careful that no one notices him, and to be sure to bring his pistols. You have yours, have you not, Mr. Knox?"

"Yes; do you expect to need them?"

"It is quite possible, as we shall have some risky work to-night. I will meet you outside, and you must tell Green to prepare for a march. Luckily we are all good walkers."

Knox hurried away, and, in a short time, both of my detectives joined me in the street. We then hired a hack and drove to within half a mile of the graveyard, where I paid off the hackman, and we entered the grounds of a residence, standing some distance back from the road. My object in entering these grounds, was to make the hackman believe we were stopping there; otherwise, his curiosity would have been excited as to my reasons for going into the country at that hour of the night. As soon as the hack was out of sight, we returned to the highway, and, after a brisk walk, we reached the graveyard.
