"What do we know about it? Do we know how Essarès met his death? Certainly it was not Siméon who killed him, as Siméon was at the hospital. But he may have caused him to be killed. And revenge has a thousand ways of manifesting itself. Lastly, Siméon was most likely obeying instructions that came from my father. There is little doubt that he wanted first to achieve an aim which my father and your mother had at heart: the union of our destinies, Coralie. And it was this aim that ruled his life. It was he evidently who placed among the knick-knacks which I collected as a child this amethyst of which the other half formed a bead in your rosary. It was he who collected our photographs. He lastly was our unknown friend and protector, the one who sent me the key, accompanied by a letter which I never received, unfortunately." "Then, Patrice, you no longer believe that he is dead, this unknown friend, or that you heard his dying cries?" "I cannot say. Siméon was not necessarily acting alone. He may have had a confidant, an assistant in the work which he undertook. Perhaps it was this other man who died at nineteen minutes past seven. I cannot say. Everything that happened on that ill-fated morning remains involved in the deepest mystery. The only conviction that we are able to hold is that for twenty years Siméon Diodokis has worked unobtrusively and patiently on our behalf, doing his utmost to defeat the murderer, and that Siméon Diodokis is alive. Alive, but mad!" Patrice added. "So that we can neither thank him nor question him about the grim story which he knows or about the dangers that threaten you." * * * * * Patrice resolved once more to make the attempt, though he felt sure of a fresh disappointment. Siméon had a bedroom, next to that occupied by two of the wounded soldiers, in the wing which formerly contained the servants' quarters. Here Patrice found him. He was sitting half-asleep in a chair turned towards the garden. His pipe was in his mouth; he had allowed it to go out. The room was small, sparsely furnished, but clean and light. Hidden from view, the best part of the old man's life was spent here. M. Masseron had often visited the room, in Siméon's absence, and so had Patrice, each from his own point of view. The only discovery worthy of note consisted of a crude diagram in pencil, on the white wall-paper behind a chest of drawers: three lines intersecting to form a large equilateral triangle. In the middle of this geometrical figure were three words clumsily inscribed in adhesive gold-leaf: _The Golden Triangle_ There was nothing more, not another clue of any kind, to further M. Masseron's search. Patrice walked straight up to the old man and tapped him on the shoulder: "Siméon!" he said.
