"Thou'lt come with me and hush thy whining!"

They had reached a lane between the houses, unpaved, trampled hard and uneven by many feet. This lane was known then as the Street of the Black Dog; and it ended abruptly at the low stone wall which here marked the boundary of Saint Peter's land. By the wall, at the head of the street, was one of the rude stone crosses which were raised at intervals around the walls and at every gate therein. This was forty or fifty yards ahead of them as they stood. As Valerius touched the girl she sprang away from him and fled forward up the street, with head thrown back and torn rags fluttering and her black hair streaming behind her in a cloud. Valerius shouted and plunged after her, a hand outstretched with clutching fingers. And after them went Nicanor, his eyes alight with the lust of the chase, the fierce joy of the hunting, old as mankind itself. As Valerius snatched at a rag on the girl's shoulder, he gave a sharp yelp of triumph, as a hound yells when its leash-mate has nipped the fox. But the rag tore away as the girl struggled free. She reached the head of the street, a flying figure of terror, with the black-browed Roman at her heels and Nicanor racing alongside; staggered, recovered, stumbled again even as he touched her, and fell forward at the foot of the stone cross, with a sob like that of a horse ridden to the death, clasping the column with both hands and crying:

"I claim sanctuary! I claim sanctuary!"

Then her head fell forward on her outflung arms, and she lay with thin shoulders heaving to her fighting breath, and her face hidden in her tangled mane. Valerius stopped, almost in his stride, all but overrunning her, so close upon her had he been. He shook his balled fist and cursed her, glaring down upon her, not daring to touch so much as a strand of hair. For she was in the shelter of holy Church; and few men were bold enough to violate that terrible, wonderful Law of Sanctuary which even then was beginning to be dreaded and respected, and which high and low might claim alike. So that Valerius walked in half-circles about her, like a baffled beast which sees its prey torn from its very jaws; and she lay and shuddered, and Nicanor stood watching with avid eyes. For as yet he was only a very primitive young animal, with the instinct of his kind to join with the hunter against the hunted. People began to gather, quickly, clamoring with question and theory; and upon these Valerius scowled, biting his nails in fury. The girl raised herself, crouching close beneath the cross, and looked around her like a trapped thing, crying:

"A priest! Is there no Christian priest here who will tell this man that I be safe from him in sanctuary?"

Valerius pulled Nicanor to him.

"Go thou and find one," he said harshly; "for while she sticketh to this cross I dare not lay finger upon her lest I be torn limb from limb by fools. He can but give her up; for she is bought and paid for, and it is not hers to say whether she finds her master to her liking. And quick with thee, that I may get her where she cannot fly again."

So Nicanor went swiftly through the nearest gate into the yard of the church, and looked about him for a priest. And it seemed to him that the more hasty grew his search, the less was it rewarded, for he was in a desperate hurry to get back and see what followed. Presently, ahead of him, he saw a priest, whom he knew as Father Ambrose, and he ran to him, shouting:

"Holy Father, a slave hath claimed sanctuary at the cross by the Street of the Black Dog, and asketh for a priest to confirm her right."

The good Father kilted up his gown, and together they ran through the nearest byway to that street. And then, quite suddenly, as they reached the end of it, Nicanor felt with a shock that he must have mistaken the place. For although the cross was there, and the wall, and the street was the Street of the Black Dog, yet there was no sign of the girl, nor of Valerius, nor of any of those who had gathered to look on. So that Nicanor turned to Father Ambrose with a face of pure fright, and stammered:
