"It was a fantastic coincidence," reflected Horne Fisher. "It's extraordinary what coincidences do sometimes occur. By the oddest chance in the world, by one chance in a million, it so happened that another sword of exactly the same shape was in the same garden at the same time. It may be partly explained, by the fact that I brought them both into the garden myself . . . come, my dear fellow; surely you can see now what it means. Put those two things together; there were two duplicate swords and he took off his coat for himself. It may assist your speculations to recall the fact that I am not exactly an assassin." "A duel!" exclaimed March, recovering himself. "Of course I ought to have thought of that. But who was the spy who stole the papers?" "My uncle was the spy who stole the papers," replied Fisher, "or who tried to steal the papers when I stopped him--in the only way I could. The papers, that should have gone west to reassure our friends and give them the plans for repelling the invasion, would in a few hours have been in the hands of the invader. What could I do? To have denounced one of our friends at this moment would have been to play into the hands of your friend Attwood, and all the party of panic and slavery. Besides, it may be that a man over forty has a subconscious desire to die as he has lived, and that I wanted, in a sense, to carry my secrets to the grave. Perhaps a hobby hardens with age; and my hobby has been silence. Perhaps I feel that I have killed my mother's brother, but I have saved my mother's name. Anyhow, I chose a time when I knew you were all asleep, and he was walking alone in the garden. I saw all the stone statues standing in the moonlight; and I myself was like one of those stone statues walking. In a voice that was not my own, I told him of his treason and demanded the papers; and when he refused, I forced him to take one of the two swords. The swords were among some specimens sent down here for the Prime Minister's inspection; he is a collector, you know; they were the only equal weapons I could find. To cut an ugly tale short, we fought there on the path in front of the Britannia statue; he was a man of great strength, but I had somewhat the advantage in skill. His sword grazed my forehead almost at the moment when mine sank into the joint in his neck. He fell against the statue, like Caesar against Pompey's, hanging on to the iron rail; his sword was already broken. When I saw the blood from that deadly wound, everything else went from me; I dropped my sword and ran as if to lift him up. As I bent toward him something happened too quick for me to follow. I do not know whether the iron bar was rotted with rust and came away in his hand, or whether he rent it out of the rock with his apelike strength; but the thing was in his hand, and with his dying energies he swung it over my head, as I knelt there unarmed beside him. I looked up wildly to avoid the
