Kay seized the man by the arm.

"What ails you, man? what is it?" he asked, quickly and sternly; but at that moment the pale face of Robert Catesby appeared, and he was followed by a tall bearded man of very soldierly bearing, who said, in calm, authoritative accents:

"I have here some holy water, blessed by the Pope himself. If we do but sprinkle the walls with that and bid the daring fiend cease, all will be well. It is no work of God; it is a work of the devil, striving to turn us aside from our laudable and righteous purpose. Prove me if it be not so. If yon booming bell sounds again after this holy water has been sprinkled, then will I own that it is God fighting against us; but if it cease after this has been sprinkled, then shall we know that heaven is on our side and only the powers of darkness against us."

"So be it," answered Catesby, quickly and decisively; "thou shalt make trial of it, good Guido. I trow we shall learn by that token that God is on our side."

All this Cuthbert saw and heard, as he stood in the shadow at the top of the stairs consumed by a burning curiosity. Something had occurred of such overwhelming interest as to obliterate even from Kay's mind for the moment the errand on which he had come, and his presence in the house at this moment awoke no question amongst the men assembled there, who were plainly otherwise engrossed. All vanished again down the stairs, and Cuthbert stole after them with cautious footfalls, too eager to discover what could be so moving them to consider what he was doing.

It was easy to track, by their voices and the light they carried, the men who had preceded him. The long flight of stairs terminated in a long stone passage, deadly cold; and this led in turn to a great cellar, at the far end of which a group of seven men was assembled. They appeared to be standing round the entrance to a small tunnel, and this tunnel they had plainly been making themselves; for a number of tools for boring and picking lay about, and the faces, hands, and clothes of the assembled party plainly indicated the nature of their toil, albeit from their speech and bearing it was plain that all were gentlemen.

Robert Catesby was sprinkling the walls of this tunnel with some water, using words of supplication and exorcism, and his companions stood bare headed around him. A great hush fell upon all as this ceremony ceased, and all seemed to listen intently.

"There is no sound; the devil hath taken flight. I knew how it would be!" spoke the tall dark man exultantly. "And now, comrades, to work again, for we have heard the last of our knell tonight. No powers of darkness can stand before the charm of His Holiness's power."

With an air of relief and alacrity the gentlemen seized their tools, and again the hollow or ringing sounds commenced to sound in that dim place; but Kay had plucked Robert Catesby by the sleeve, and was whispering some words in his ear.

Catesby turned quickly round, made a few strides towards the staircase, and then catching sight of Cuthbert, stopped short, and seized Kay by the arm.
