The moment I caught sight of Terry as he swung off the train I felt involuntarily that my troubles were near their end. His sharp, eager face with its firm jaw¹ and quick eye inspired one with the feeling that he could find the bottom of any mystery. It was with a deep breath of relief that I held out my hand.
 
"Hello, old man! How are you?" he exclaimed with a smile of cordiality as he grasped it. And then recalling the gravity of the situation, he with some difficulty pulled a sober face. "I'm sorry that we meet again under such sad circumstances," he added perfunctorily. "I suppose you think I've meddled² enough in your affairs already; and on my word, I intended to stay out of this. But of course I've been watching it in the papers; partly because it was interesting and partly because I knew you. It struck me yesterday afternoon as I was thinking things over that you weren't making much headway and might like a little help; so I induced the Post-Dispatch to send down their best man. I hope I shall get at the truth." He paused a moment and looked at me sharply. "Do you want me to stay? I will go back if you'd rather have me."
 
I was instantly ashamed of my distrust of the afternoon. Whatever might be Terry's failings, I could not doubt, as I looked into his face, that his Irish heart was in the right place.
 
"I am not afraid of the truth," I returned steadily³. "If you can discover it, for Heaven's sake do so!"
 
"That's what I'm paid for," said Terry. "The Post-Dispatch doesn't deal in fiction any more than it can help."
 
As we climbed into the carriage he added briskly, "It's a horrible affair! The details as I have them from the papers are not full enough, but you can tell them to me as we drive along."
 
 
I should have laughed had I been feeling less anxious. His greeting was so entirely⁴ characteristic in the way he shuffled⁵ through the necessary condolences and jumped, with such evident relish⁶, to the gruesome details.
 
As I gathered up the reins⁷ and backed away from the hitching-post, Terry broke out with:
 
"Here, hold on a minute. Where are you going?"
 
"Back to Four-Pools," I said in some surprise. "I thought you'd want to unpack⁸ your things and get settled."
 
"Haven't much time to get settled," he laughed. "I have an engagement in New York the day after to-morrow. How about the cave? Is it too late to visit it now?"
 
"Well," I said dubiously⁹, "it's ten miles across the mountains and pretty heavy roads. It would be dark before we got there."
 
"As far as that goes, we could visit the cave at night as well as in the daytime. But I want to examine the neighborhood and interview some of the people; so I suppose," he added with an impatient sigh, "we'll have to wait till morning. And now, where's this young Gaylord?"
 
"He's in the Kennisburg jail."
 
"And where's that?"
 
"About three miles from here and six miles from the plantation¹⁰."
 
"Ah—suppose we pay him a visit first. There are one or two points concerning his whereabouts on the night of the robbery and his actions on the day of the murder that I should like to have him clear up."
 
I smiled slightly as I turned the horses' heads toward Kennisburg. Radnor in his present uncommunicative frame of mind was not likely to afford Terry much satisfaction.
 
"There isn't any time to waste," he added as we drove along. "Just let me have your account of everything that happened, beginning with the first appearance of the ghost."
 
I briefly¹¹ sketched¹² the situation at Four-Pools as I had found it on my arrival, and the events preceding the robbery and the murder. Terry interrupted me once or twice with questions. He was particularly interested in the three-cornered situation concerning Radnor, Polly Mathers, and Jim Mattison, and I was as brief as possible in my replies; I did not care to make Polly the heroine of a Sunday feature article. He was also persistent¹³ in regard to Jefferson's past. I told him all I knew, added the story of my own suspicions, and ended by producing the telegram proving his alibi¹⁴.
 
"H'm!" said Terry folding it thoughtfully and putting it in his pocket. "It had occurred to me too that Jeff might be our man—this puts an end to the theory that he personally committed the murder. There are some very peculiar¹⁵ points about this case," he added. "As a matter of fact, I don't believe that Radnor Gaylord is any more guilty of the crime than I am—or I shouldn't have come. But it won't do for me to jump at conclusions until I get more data. I suppose you realize what is the peculiarly significant point about the murder?"
 
"You mean Mose's disappearance¹⁶?"
 
"Well, no. I didn't have that in mind. That's significant enough to be sure, but nothing but what you would naturally expect. The crime was committed, if your data is straight, either by him or in his presence, and of course he disappears. You could scarcely have expected to find him sitting there waiting for you, in either case."
 
"You mean Radnor's behavior on the day of the murder and his refusal to explain it?" I asked uneasily.
 
"No," Terry laughed. "That may be significant and it may not—I strongly suspect that it is not. What I mean, is the peculiar place in which the crime was committed. No person on earth could have foreseen that Colonel Gaylord would go alone into that cave. There is an accidental element about the murder. It must have been committed on the spur of the moment by someone who had not premeditated it—at least at that time. This is the point we must keep in mind."
 
He sat for a few moments staring at the dashboard with a puzzled frown.
 
"Broadly speaking," he said slowly, "I have found that you can place the motive¹⁷ of every wilful¹⁸ murder under one of three heads—avarice¹⁹, fear or revenge. Suppose we consider the first. Could avarice have been the motive for Colonel Gaylord's murder? The body had not been robbed, you tell me?"
 
"No, we found a gold watch and considerable money in the pockets."
 
"Then, you see, if the motive were avarice, it could not have been immediate²⁰ gain. That throws out the possibility that the murderer was some unknown thief who merely took advantage of a chance opportunity. If we are to conceive of avarice as the motive, the crime must have been committed by some person who would benefit more remotely by the Colonel's death. Did anyone owe him money that you know of?"
 
"There is no record of anything of the sort and he was a careful business man. I do not think he would have loaned money without making some memorandum²¹ of it. He held several mortgages but they, of course, revert²² to his heirs."
 
"I understood that Radnor was the only heir."
 
"He is, practically. There are a few minor²³ bequests²⁴ to the servants and to some old friends."
 
"Did the servants know that anything was to go to them?"
 
"No, I don't think they did."
 
"And this Cat-Eye Mose, did he receive a share?"
 
"Yes, larger than any of the others."
 
"It seems that Colonel Gaylord, at least, had confidence in him. And how about the other son? Did he know that he was to be disinherited?"
 
"I think that the Colonel made it plain at the time they parted."
 
Terry shook his head and frowned.
 
"This disinheriting business is bad. I don't like it and I never shall. It stirs up more ill-feeling than anything I know of. Jeff seems to have proved an alibi, however, and we will dismiss him for the present."
 
"Rad has always sympathized with Jeff," I said.
 
"Then," continued Terry, "if the servants did not know the contents of the will, and we have all of the data, Radnor is the only............
