Paul remained looking from the one to the other without speaking. It was Don Caesar who returned his glance boldly and defiantly, Colonel Pendleton who, with thin white fingers pulling his moustache, evaded it. Then Paul unlocked the door, and said slowly, "In five minutes I leave this house for the station. I shall wait there until the train arrives. If this gentleman does not join me, I shall be better able to understand all this and take measures accordingly." "And I tell to you, Meester Hathaway, sir," said Don Caesar, striking an attitude in the doorway, "you shall do as I please--Caramba!--and shall beg"-- "Hold your tongue, sir--or, by the Eternal!"--burst out Pendleton suddenly, bringing down his thin hand on the Mexican's shoulder. He stopped as suddenly. "Gentlemen, this is childish. Go, sir!" to Don Caesar, pointing with a gaunt white finger into the darkened hall. "I will follow you. Mr. Hathaway, as an older man, and one who has seen a good deal of foolish altercation, I regret, sir, deeply regret, to be a witness to this belligerent quality in a law-maker and a public man; and I must deprecate, sir--deprecate, your demand on that gentleman for what, in the folly of youth, you are pleased to call personal satisfaction." As he moved with dignity out of the room, Paul remained blankly staring after him. Was it all a dream?--or was this Colonel Pendleton the duelist? Had the old man gone crazy, or was he merely acting to veil some wild purpose? His sudden arrival showed that Yerba must have sent for him and told him of Don Caesar's threats; would he be wild enough to attempt to strangle the man in some remote room or in the darkness of the passage? He stepped softly into the hall: he could still hear the double tread of the two men: they had reached the staircase--they were DESCENDING! He heard the drowsy accents of the night porter and the swinging of the door--they were in the street! Wherever they were going, or for what purpose, HE must be at the station, as he had warned them he would be. He hastily threw a few things into his valise, and prepared to follow them. When he went downstairs he informed the porter that owing to an urgent call of business he should try to catch the through express at three o'clock, but they must retain his room and luggage until they heard from him. He remembered Don Caesar's letter. Had either of the gentlemen, his friends who had just gone out, left a letter or message? No, Excellency; the gentlemen were talking earnestly--he believed, in the South American language--and had not spoken to him.
