"On the evening when, from the inner gallery of the library, you witnessed the tragedy at Essarès' house, you saw before your eyes two men bound by their accomplices: Essarès Bey and Siméon Diodokis. They are both dead. One of them was your father. Let us speak first of the other. Essarès Bey's position was a critical one that evening. After draining our gold currency on behalf of an eastern power, he was trying to filch the remainder of the millions of francs collected. The _Belle Hélène_, summoned by the rain of sparks, was lying moored alongside Berthou's Wharf. The gold was to be shifted at night from the sand-bags to the motor-barge. All was going well, when the accomplices, warned by Siméon, broke in. Thereupon we have the blackmailing-scene, Colonel Fakhi's death and so on, with Essarès learning at one and the same time that his accomplices knew of his schemes and his plan to pilfer the gold and also that Colonel Fakhi had informed the police about him. He was cornered. What could he do? Run away? But, in war-time, running away is almost impossible. Besides, running away meant giving up the gold and likewise giving up Coralie, which would never have done. So there was only one thing, to disappear from sight. To disappear from sight and yet to remain there, on the battlefield, near the gold and near Coralie. Night came; and he employed it in carrying out his plan. So much for Essarès. We now come to Siméon Diodokis." Don Luis stopped to take breath. Patrice had been listening eagerly, as though each word had brought its share of light into the oppressive darkness.
