"You see," he said, "we are few here, and I have been kept busy with the brewing uneasiness in town and cannot handle the murder affair satisfactorily. I have come to ask you to help me, if you are sufficiently at leisure. We cannot get any clues at all, save that the man was killed by a bullet of large calibre in the hands of a good shot, as the distance from which it was fired would seem to show. The road has been searched but nothing found, and the crowd that went with you to the dying man's side trampled away all clues on the ground.

"My men have reported to me the curious affair of last night," continued the Chief. "I suppose you have a explanation for it; in any event, it must be followed up. The people must be diverted, and more must be done at once than I can do. Will you help me?"

"Yes," said Oakes. "Of course!"

"h.e.l.lo, what ails your head?" said the Chief, after thanking him.

And then Oakes told him as much as was necessary of the events of the day before.

"I am very glad your _carpenters_ have arrived," said the Chief; "they may help." He smiled, as did Oakes. They understood one another--they were in similar lines of business.

"Now that I have a hand in this thing, let's all get acquainted," said Oakes; and he called in Moore and Elliott, and the discussion became general.

Elliott was admitted unreservedly to our councils, especially as Oakes knew that he held the keys to the conviction of the a.s.sa.s.sin--the witness.

Oakes, in his fluent style, acquainted the Chief with the fact that the negro was already under surveillance and that, in his opinion, he should be brought to Mona for further examination.

"Yes, but we must smuggle him in. It would be unwise to let the populace know we have him now; they might infer he was the murderer and violence would certainly be done him. At present, I have all I can do to keep order in the town," said Hallen.

Then he gave a lucid account of the wave of suspicion and of the evidences of nervous tension the citizens were showing.

"Why," said he, "almost every man suspects his neighbor. Life-long friends are suspicious of one another and business is nearly at a standstill. One man looked at another in an absent-minded sort of a way to-day, and the other retaliated with a blow and an oath, and asked him if he would look at his own arms--not his neighbor's."

"Yes," said Oakes, "we have here a great mental emotion--_suspicion_--to deal with, which may amount to a public calamity unless checked. One must always take account of the actions and reasonings of communities.

Emotional waves rush through them as through individuals sometimes. Look at history, and consider the waves of religion, emotional in character, that have occurred. Look at the unreasonableness developed in our own country from ignorance and fear, when witches were burned at the stake!"

"Oakes," said Moore with a smile, "you seem to make mental processes and conditions as much of a study as the physician does."

"Certainly," Oakes replied. "It is most important. Did we not study the workings of a criminal's mind, for instance, we would often be baffled.

You see, the determination of the probable condition of such a one's mind is often paramount, especially in such a case as this. In other words, was the _motive_ one that would naturally sway an ordinary healthy individual under the conditions appertaining to the crime--the so-called _sane_ motive? Or was it in any way dependent upon peculiarities of the criminal's reasoning--a motive built up of something unreal, a _delusion_ in the mind of one not in his right senses?"

I myself had frequently had cause to study such mental processes in the practice of my profession, but I was amazed at the knowledge shown by Oakes, and stated in such a broad, untechnical manner. The man was no ordinary one, to be sure, but I had scarcely expected him to show such education in these matters.

I now recalled what Moore had once told me of Oakes's all-round attainments.

Dr. Moore broke the silence.

"You are a lalapazooza, Oakes."

Oakes did not notice the remark, but said: "I don't know what other men do, but I have tried to bear in mind such things."

"Yes," said Hallen, "and consequently there is only _one_ Quintus Oakes."

"It seems to me," continued Hallen, "that your work here at the Mansion will soon lead to results, and I trust that you will find time to consider the murder also."

"Gentlemen," said Oakes very seriously, "from what I saw after the Mark murder in town and from what you report, I feel that Mona is in a very serious plight. I shall make time, Hallen, to do what little I can."

And thus Quintus Oakes became the leader in the unravelling of the Mark murder mystery.

After a few remarks of no particular consequence and a more or less general conversation, he resumed:

"Suppose, Chief, that we now smuggle the negro into Mona as soon as possible, and bring him here. I believe that if Mr. Elliott goes back with Martin and they explain things to the boy, he will come without much trouble. It must be impressed upon him that he is regarded in the light of a _hero_: appeal to the innate weakness of the race--desire for flattery."

"I believe we can bring him here easily," said Elliott, "for he has confidence in me."

"If he refuses to come," said Hallen, "we can get him here in plenty of ways."

"Yes," said Oakes, "Martin knows how; leave it to him. Only, we must have him soon, and he must come here by way of another station, incognito, lest the people become too excited."

This being agreed upon, the conversation became more general, and in answer to questions we found that Oakes had not as yet formulated any solution to the mystery of the ident.i.ty of the murderer. As he said, the affair of downstairs might be connected with the murder, indirectly or directly, but as yet we had not had sufficient opportunities for studying the surroundings of the house or the life of its attaches to venture an opinion. He laid particular stress upon the fact that opinions should never be formed on poor evidence, since a biased mind was incapable of appreciating new discoveries or new clues. To theorize too much was very easy, but sometimes fatal to detection of crime. He preferred to work along several lines of investigation before concentration on any one idea.

"The affair of last night, in my estimation," said he, "is one of very grave import. Unquestionably, from what you saw, Stone, and from the evidence of us all, there were two men near the place you were going to pa.s.s. That the first one warned you and was, in a sense, a friend, is mysterious enough--it needs solution; but that the man who warned you should have run away and been pursued by the other is peculiar, to say the least. The signals of your companions were heard by the man at the bridge undoubtedly, and he ran to escape detection himself. The other--the one on this side, who was a probable a.s.sa.s.sin--would under ordinary circ.u.mstances have run away when he saw you were warned. He did run, but it was after the man who warned you."

"To my mind, the explanation is this," continued the detective. "The man at the bridge is friendly, but cannot expose his ident.i.ty or risk capture. The would-be a.s.sa.s.sin was convinced that the man who warned you knew of his purpose. He therefore pursued him--to finish him in self-protection."

"I don't see why," said Moore; "he could have escaped instead."

"Exactly," said Oakes. "He could have done so, but he did not wish it.

He has not completed what he wants to do around here. He wished to come back, and to do so with safety he must rid himself of the one who knew of his doings."

"Looks as though he was planning more trouble. He may have been the man of the robe, or the man with the arms," I ventured.

"Or both," said Oakes.

"At all events," said Hallen, "I wish that we could divert the minds of the people in town; the tension is great--too great for safety."

"Perhaps, Chief," said Oakes, "that you and I can arrange a little matter that will distract their attention and which will tend to make them believe that progress is being made."

He laughed as he spoke, and we knew that he was thinking over some little scheme to help Hallen back into popular favor.

_CHAPTER XIV_

_Clues_

The carpenters and masons came and went in a very business-like way all that morning, while we were closeted upstairs with our companion and Chief Hallen.

After he left us, Moore and I walked down to the gate and around the grounds, leaving Oakes to attend to details with Martin. Carpenters were very busy around the dining-room, carrying in boards and implements, and examining the woodwork and the balcony.

A few of the masons were about the grounds, engaged on small details, and all seemed to be on good terms with Cook and his wife, and Annie.

Mike was busy at one end of the garden, and Maloney was not far off.

"This, Stone, is to be a day of events here. But things are being done very quietly, are they not? You would suspect nothing out of the way--far less a hunt for a murderer or the investigation of a mystery, would you?"

"No; were I not informed, I should think that Oakes had merely a gang of laborers at work."
