"You must have a sergeant and guard billeted here!" was his first sharp word; and the widow had sighed at this invasion of their privacy, which was also their poverty. But the young girl, standing sideways in that very window, which was to be closed, had pouted her red lips and frowned on the intruder, and the sergeant had not come, nor the guard. Instead the young man had returned, at first weekly, then at shorter intervals, to see that the window defences remained intact; and with his appearance life in the House on the Wall had become a different thing. He was the son of the Burgomaster of the town, he would be the richest man in the town, his wife might repay with interest and advantage the dull bovine scorn to which the city dames had treated her mother. The widow permitted herself to hope. Her child was beautiful, with the creamy fairness of Gueldres, and as pure as the sky. The young man was gay and handsome; qualities which made their due impression on the elder woman's heart, long unfamiliar with them. So, for more than a year he had had the run of the house, he had been one of the family; and then one day he had disappeared, and then one other day——

Oh, God of vengeance! She paused in the darkening street, as she thought of it. Beside her a long window, warmly curtained, sent out a stream of ruddy light. From the opposite house issued cheery voices and tinkling laughter, and the steam of cooking. And before and behind, whichever way she looked, firelight flashed through diamond panes and glowed in the heart of green bottle-glass. Out in the street men shouldered past her, talking blithely; and in distant kitchens cups clinked and ware clattered, and every house—every house from garret to parlour, seemed to her a home happy and gleeful. A home; and her home! She stood at the thought and cursed them; cursed them, and like the echo of her whispered words the solemn boom of a cannon floated over the town.

A chance passer, seeing her stand thus, caught the whiteness of her face, and thought her afraid. "Cheer up, mother!" he said over his shoulder, "they are all bark and little bite!"

"I would they bit to the bone!" she cried in fury.

But luckily he was gone too far to hear or to understand; and, resuming her course, she hurried on, her head bowed. A few minutes' walking brought her to the foot of the stone steps that, in two parallel flights, led up to the low-browed door of her house. There, as she set her foot on the lowest stair, and wearily began the ascent, a man advanced out of the darkness and touched her sleeve. For an instant she thought it the man, and she caught her breath and stepped back. But his first word showed her her mistake.

"You live here?" he said abruptly. "Can I come in?"

In ordinary times his foreign accent and the glint of a pistol-barrel, which caught her eye as he spoke, would have set her on her guard. But to-night she had nothing to lose—nothing, it seemed to her, to hope. She scarcely looked at the man. "As you please," she said dully. "What do you want?"

"To speak to you."

"Come in then," she said.

She did not turn to him again until they stood together in the room above, and the door was shut. Then she asked him a second time what he wanted.
