The captain's wife had the presence of mind to hold up the lantern, so that the light fell full upon the helmet Zeno wore. Instantly the soldier tried to straighten himself to an attitude of attention, with his hands by his sides. But this was too much for his unstable balance, and he reeled backwards half across the room within, till he struck the table behind him, and tumbled down with a clatter of accoutrements and a rattling of the horn drinking-cups that were thrown to the ground. His companion, who was altogether too drunk even to leave his seat, broke into a loud idiotic laugh at his accident. 'You have done your share well, Kyría,' said Zeno, as he followed her again. 'The Emperor's friends could have brought him down by the stairs in triumph without being stopped.' 'You are not out of the palace precincts yet,' answered the captain's wife in a warning tone. She went on, treading more softly as she descended, and carrying the lantern low lest she or her companion should stumble over another sleeping sentinel; but the staircase and the door that led into the court were deserted, for the captain was a very exact man, and had his supper at the same hour every evening, and went to bed soon afterwards like an honest citizen, after setting the watch and locking the iron door of his own lower landing. In two years he had never once come down the tower after sunset. The consequence was that the guards, who were mostly rough barbarians from the Don country and the shores of the Black Sea, did as they pleased, or as their lieutenant pleased; for he found it pleasant to spend his nights in another part of the palace, and was extremely popular with his men, because they were thus enabled to go to bed like good Christians and sleep all night. All this the captain's wife knew well enough. Her apprehension was for what might happen to Zeno between leaving the tower and passing the great gate, which was the only way to get out of the fortified precincts. The wide courtyard was very dark, but there were lights here and there in the windows of the buildings that surrounded it on three sides, the great mass of the palace on the right, the barracks of the guards along the wall to the left, and the main post at the great gate in front with the buildings on each side of it, some occupied by slaves and some used as stables.
