“Yes?” he said.

“And the chapels will be down immediately. Oh! dear God!”

Dom Anthony made room for the old man to sit down in the window-seat; and himself stood behind the two with Nicholas; and so again they watched.

The light was fading fast now, and in the windows below lights were beginning to shine. The square western tower that dominated the whole priory had lost its splendour, and stood up strong and pale against the meadows. There was a red flare of light somewhere over the wall of the court, and the inner side of the gate-turret was illuminated by it.

A tense excitement lay on the watchers; and no sound came from them but that of quick breathing as they waited for what they knew was imminent.

Outside the evening was wonderfully still; they could hear two men talking somewhere in the street below; but from the priory came no sound. The chink of the picks was still, and the cries of the workmen. Far away beyond the castle on their left came an insistent barking of a dog; and once, when a horseman rode by below Chris bit his lip with vexation, for it seemed to him like the disturbing of a death bed. A star or two looked out, vanished, and peeped again from the luminous sky, to the south, and the downs beneath were grey and hazy.

All the watchers now had their eyes on the eastern end of the church that lay in dim shadow; they could see the roof of the vault behind where the high altar lay beneath; the flying buttress of a chapel below; and, nearer, the low roof of the Lady-chapel.

Chris kept his eyes strained on the upper vault, for there, he knew the first movement would show itself.

The time seemed interminable. He moistened his dry lips from time to time, shifted his position a little, and moved his elbow from the sharp moulding of the window-frame.

Then he caught his breath.
