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.
