CHAPTER VIII.

[A CLEW TO THE MYSTERY.]

The drama of "The Prodigal Son" was enacted over again when I returned to Marshminster. My aunts had greatly resented my sudden departure to Paris, and announced that this time intended to keep me them for some weeks. I had no objection to this arrangement, as I anticipated a long and laborious task in ferreting out evidence against Felix. The first thing to be done was to learn all that had taken place in my absence, and the information was ably supplied by Aunt Jane, seconded by her sister. I inquired about Briarfield and his fiancée.

"Bellin Hall is to be shut up next week," said Aunt Jane; "the Bellins are going to town, and with them Mr. Briarfield.

"I wonder they stayed here so long when the season was on in London," said Aunt Sophia, "but it was all that foolish Mrs. Bellin. She chose to consider herself ill, and so insisted upon remaining here. Now she can't resist the attractions of town life any longer, and goes next week."

"She has to arrange about the wedding, Sophia. You know it takes place in July. I wonder if Mr. Felix Briarfield will be back in time to be best man."

"That I can safely say is impossible," said I dryly.

"But why?" exclaimed both the old ladies, scenting news.

"Well, he has gone to Italy, and from there goes to the East," I answered, unwilling to tell the truth. "I don't see how he can return in time for the wedding if it takes place in July."

My female relatives looked significantly at one another.

"What did I tell you, Sophia?" said Aunt Jane in a tone of subdued triumph.

"Yes, sister, you were right," sighed Sophia, shaking her head. "Poor young man. I thought myself he loved Olivia."

"Who loved Olivia?" I asked sharply.

"Felix Briarfield," said Aunt Jane; "when his brother went to America, he was always with her, and no doubt loved her dearly. I can scarcely wonder at that, as she is so beautiful a girl. But he behaved very well, and when Francis came back, went to the Continent."

"He was unable to bear the sight of his brother's happiness," said Aunt Sophia sentimentally; "poor, poor young man! I have no doubt his heart is broken. He actually left Marshminster before his brother arrived from America, so as to spare himself the painful sight of their happiness."

I saw by this conversation that my surmise was correct. Felix had fallen in love with Olivia while his brother was in America, and, selfishly determined not to give her up, had devised the idea of passing himself off as Francis. With this in his mind he had gone to Paris, and pretended to stay there; then reappeared at Marshminster as Francis, alleging an earlier return from Chili as an excuse. When Francis really returned, Felix asked him to be at the Fen Inn, so as to rid himself of his brother before he could see Olivia. Whether he intended to kill Francis or to merely explain matters I could not tell, but at all events Francis had been murdered, and I firmly believed that Felix was morally guilty of the crime. The suppression of the letters, the substitution of himself as Francis, and the dexterous manner in which he had rid himself of the corpse (according to Merrick's theory), all showed me that I had a dangerous and reckless man to deal with. But after the clever way in which he had baffled me in Paris by resuming his name I was prepared for any villainy at his hands. He had committed himself so far that he could not draw back, and was compelled to follow crime by crime in order to bolster up his position.

He was going to town with the evident intention of evading me. Doubtless he thought that, deceived by the episode at the Hôtel des Étrangers, I had quite abandoned all idea of meddling in the affair. But for Merrick I should certainly have done so. Now that Merrick saw the matter in the same light as I did, I was determined to go on, but resolved to give no hint of this to Felix. When he left Marshminster, I could pursue my inquiries at leisure. Already I had been too rash in revealing my intentions, for had I not mentioned my journey to Paris, Felix would not have been put on his guard and baffled me so adroitly.

I had at least gained one important piece of information, which in itself was sufficient to break off the match. The passenger list of the _Copiapo_ proved conclusively that Francis had not reached England before the 6th of June, and this shown to Olivia would show that Felix was passing himself off as her lover. With such proof I could stop the marriage immediately, but preferred to wait until I gained further evidence implicating him in the murder of his brother. I believed Merrick's theory to be true, and quite expected to find that Felix had ridden out to the Fen Inn for the purpose of hiding his brother's body in one of the bogholes.

"By the way," I asked Aunt Jane, as we parted for the night, "how does Miss Bellin look? Like a happy bride! eh?"

"By no means," replied my aunt solemnly; "she looks ill and miserable. But that I know this marriage with Francis is a love match, I should say she disliked the idea of becoming his wife."

"No doubt," thought I, "no doubt. Olivia mistrusts Felix already."

I said good-night to my elderly relative, and went off to bed. Instead of turning in I lighted my pipe and leaned out of the window, thinking deeply. Could it be possible that Olivia had discovered the imposture? If so, why did she tamely submit to marry a man whom she must know was guilty of his brother's and her lover's death? Moreover, if she were assured of this, she must also have condoned the deception at the Hôtel des Étrangers. Her conduct seemed strange, yet I could not bring myself to believe that she knew the truth. If she did, she was as bad as Felix.

"She must think he is really Francis, and that Felix is in Paris," I thought. "Surely she would not willingly go to the altar with a man whom she knows to be a villain. No! He has thrown dust in her eyes, and made her believe what he pleases. I must save the poor girl from such a fate. Perhaps, in spite of outward semblance, she instinctively feels that Felix is not Francis. Women have their instincts. I know of no other reason why she should look pale and ill."

My cogitations were cut short by Aunt Jane knocking at the door and telling me not to waste the candles. I was used to these little idiosyncrasies of my aunts, so I answered that I was going to bed, and put out the light at once, but the rest of the night was passed in a wakeful state. Truly, I had a bad attack of detective fever!

For the next few days I kept very quiet, as I was unwilling to rouse the suspicions of Felix. At length, my aunts, who entertained no suspicion of my designs, informed me that he had gone to London with Mrs. and Miss Bellin. The coast now being clear, I ventured out and began to work out my carefully-laid plans.

In the first place I went to Bob Fundy to hire a horse. It was my intention to ride out to the Fen Inn and thoroughly examine the rooms, as I fancied Felix might have hidden the corpse in the house. From Fundy I gained a piece of unexpected information.

"Want to ride to the Fen Inn, sir," said he, scratching his head. "Why, whatever's come over that old ruin? Everyone seems to be going there."

"What do you mean, Fundy?"

"First Mr. Briarfield, and now you," said Fundy. "Blessed if I can understand it. Though, to be sure, he rode there at night, and you go in the daytime."

"Did Mr. Briarfield go to the Fen Inn at night?" I asked, seeing I was on the eve of learning something important. I had not forgotten Merrick's theory.

"That he did, sir. He rode there two nights over a week ago."

"Curious," said I, with assumed carelessness; "it is not an attractive place. I dare say he only rode a little way out of the town."

"No, sir," said Fundy decisively, "he went to the Fen Inn! He told me so himself, as I noticed the horse was so done up. Look here," added Fundy, opening his day-book, "see, on the 10th of June he had a horse, and on the 11th. Both at night, and did not return till midnight."

I mounted my horse and rode away, thinking deeply. If Felix had gone to the Fen Inn on the 10th, then I felt sure that he had actually murdered his brother. Hitherto I had believed Strent was the guilty party, but now, thanks to the evidence of Fundy, I saw that Felix had committed the crime. He had also ridden to the inn again on the 11th in order to conceal the body. Merrick's theory was thus proved to be correct. Link by link I was putting the chain together. I had proved that Francis had not arrived in England till the 6th of June, and so made certain of the identity of Felix. I had discovered that Felix was at the inn on the fatal night, and also that he had concealed the body. Now I wished to discover how the murder was committed.

The Fen Inn was quite deserted, and as evil-looking as ever. In spite of my searching I discovered no signs of the dead body of my friend. The clothes which I had seen folded on the chair beside the bed were also gone, and there was not the slightest thing left to excite suspicion.

"He must have hidden the body in the marshes," I thought, after a vain search; "I'll see if he has left a trail."

Struck by the feasibility of this idea, I went out at the front door and examined the ground. It was moist and muddy, owing to the incessant percolation of marshy water. The path leading from Marshminster was marked confusedly with horses' hoofs, so it was quite useless to look for a trail in that direction. Looking from the door of the inn, the path trended to the right; but on the left, where there was no path, I noticed hoof marks, also that the lush grass was trodden down.

"Here is the trail," said I, mounting my horse; "he took the body to the left."

Following the trail carefully,--and it was plainly discernible, owing to the dampness of the ground,--I rode straight out for some considerable distance. The spongy marsh jetted black water under the feet of the horse, and it seemed as though I were in danger of being bogged. Nevertheless, as the trail still continued in front of me, I followed it. Where Felix could go I could follow. He had evidently placed the body of his brother across his saddle and ridden with it in this direction; I wondered at the nerve of the scoundrel.

Unexpectedly the trail turned off at right angles, and led toward a broad pond of water, slimy and sullen in appearance. On the verge of this the track ceased, and then I knew that I saw before me the tomb of Francis Briarfield. Into those black waters the murderer had hurled his victim, and doubtless if the pool were dragged the body would be found. This I determined to do before taking further steps in the matter.

"Then, Mr. Felix Briarfield," said I, riding back to the inn, "then we will see how much your astuteness will avail you."

It was late in the afternoon when I got back to the inn, and the cold vapors of the marsh made me shiver. As I am subject to rheumatism, I was afraid of future sufferings, so, having some brandy in my flask, I determined to light a fire for the purpose of heating water, and comforting myself with a hot drink. There was plenty of fuel about, and I had matches in my pocket. I began to rake the dead ashes out of the dining-room grate, when I disturbed an oblong piece of flint which rattled on to the earth. All ideas of lighting a fire were forgotten as I stood with that in my hand. It was an arrowhead. I handled it gingerly, for I knew well that it was steeped in poison, and that with this Francis had been murdered.

I saw at once what had taken place. Felix had arrived, and had gone up to his brother's room. Holding the flint with the razorlike edge outward, he had shaken hands with his brother, and so wounded him. A quarrel had ensued, but Francis, not thinking he was poisoned, never dreamed of his danger. Then he had fallen dead, and Felix, placing the body on the bed, had returned to the dining room, and flung the poisoned arrowhead into the fire. The most astounding thing was that I had not been awakened by the outcry of Francis, but I suppose I was quite worn out by my walk and in too deep a sleep. Nevertheless, it was strange that I had heard neither the arrival of Felix nor the struggle which must have taken place. Possibly I had been drugged.

With this damning piece of evidence in my pocket, wrapped up in paper,--for I feared the poison myself,--I rode back to Marshminster, wondering how Felix had hit upon such a terribly ingenious fashion of removing his brother. So far as I knew he had not traveled much, and would not be likely to have any savage weapons in his possession; yet he could not have owned a flint arrowhead in the ordinary run of things. This puzzled me greatly.

I returned the horse to Fundy without making any remarks, and, thoroughly tired out, went early to rest, still puzzling over that arrowhead. Before dawn I solved the mystery. In the entrance hall of the Bellins' house a perfect armory of savage weapons were arrayed against the wall. There were clubs, arrows, bows, mats, and grinning heathen gods. Doubtless Felix, knowing the arrows to be poisoned, had taken the flint head of one in order to put his brother to death. As early as I could I went to Bellin Hall to satisfy myself on this point.

The Hall was a show place, as it possessed a fine picture gallery, so I had but little difficulty in gaining admission from the woman in charge. Requesting permission to examine the warriorlike implements patterned against the hall wall, I narrowly observed the arrows. It was as I thought--one of the arrows was missing, and Felix had stolen it in order to kill his brother! I did not take much interest in the pictures after such a discovery, and the talk of the housekeeper fell unheeded on my ears. Finally I gave her a sovereign, and left the house, impatient to be alone and think over my discoveries.

I had now sufficient evidence to prove that Felix had killed Francis, and quite sufficient to warrant my having him arrested. If the pool were dragged, the body would be found, with the ragged wound of the flint arrowhead on the right hand. I could prove the finding of the arrowhead in the ashes, and how it had been taken from Bellin Hall. Fundy could give evidence to Felix having taken a horse to the Fen Inn on the 10th, and also on the 11th. And, altogether, the evidence against Felix was clearly sufficient to hang him. Still, I did nothing rashly, and before taking further proceedings returned to London to consult Merrick. His advice, I knew, would be judicious.
