With an oath he crossed the hall and struck his hand against the panel indicated. No answer. He knocked again with peremptoriness, then tried the door. It was unlocked, and opened quietly to his touch. All beyond was silent and dark. "Father Tierney, I'll thank you for that candle!" The priest gave it, and the aide held it up, displaying a chill and vacant chamber, furnished with monastic spareness. There was a narrow couch that had been slept in. Marchmont crossed the bare floor, bent, and felt the bedclothing. "Quite cold. You've been gone some time, my friend. H--m! things look rather black for you!" Father Tierney spoke from the middle of the room. "It's sorry the lieutenant will be! Sure, and he thought he had the general's last word! 'Slape until you wake, my son,' says I. 'Judy will give us breakfast at eight.' 'No, no, father,' says he. 'General Kelly is wearying for this letter from General Banks. If I get it through prompt it will be remembered for me,' he says. ''T will be a point toward promotion,' he says. 'My horse has had a couple of hours' rest, and he's a Trojan beside,' he says. 'I'll sleep an hour myself, and then I'll be taking the road back to Romney. Ashby's over on the other side,' he says, 'and the sooner I get Ashby off my mind, the better pleased I'll be,' he says. And thereupon he slept for an hour--" Marchmont still regarded the bed. "I'll be damned if I know, my friend, whether you're blue or grey! How long has he been gone?" Father Tierney pondered the question. "By the seven holy candles, my son, I was that deep asleep when you knocked that I don't rightly know the time of night! Maybe he has been gone an hour, maybe more--" "And how did he know the countersign?" "Faith, and I understood that the general himself gave him the word--" "H--m!" said Marchmont, and tugged at his moustache. He stood in silence for a moment, then turned sharply. "Blue or grey, which? I'll be damned if I don't find out! Your horse may be a Trojan, my friend, but by this time he's a tired Trojan! Roberts!" "Yes, sir." "You two go at once to headquarters' stables. Saddle my horse--not the black I rode yesterday--the fresh one, Caliph. Get your own horses. Double-quick now! Ten minutes is all I give you." The men departed. Marchmont stalked out of the chamber and to the open front door. Father Tierney, repossessed of the candle, followed him. "Sure, and the night's amazing chill! By good luck, I've a fine old bottle or two--one of the brigadiers, that's a good son of the church, having sent me a present. Whist, captain! a little glass to cheer the heart av ye--" "I'll not stop now, father," said the aide dryly. "Perhaps, upon my return to Frederick I may call upon you."
