t spot. Guillaume had made the journey a
score of times at carefully selected hours, and all his powder had been
poured into the gap beside the pillar, spreading to the slightest rifts
below, saturating the soil at a great depth, and in this wise forming a
natural mine of incalculable force. And now the powder was flush with the
flagstone which Guillaume has just moved aside. It was only necessary to
throw a match there, and everything would be blown into the air!

For a moment an acute chill of horror rooted Pierre to the spot. He could
neither have taken a step nor raised a cry. He pictured the swarming
throng above him, the ten thousand pilgrims crowding the lofty naves of
the basilica to witness the solemn consecration of the Host. Peal upon

and swallowing up the whole church and its multitude of worshippers.
Breaking the concrete piles and rending the unsound soil, the explosion,
which was certain to be one of extraordinary violence, would doubtless
split the edifice atwain, and hurl one-half down the slopes descending
towards Paris, whilst the other on the side of the apse would crumble and
collapse upon the spot where it stood. And how fearful would be the
avalanche; a broken forest of scaffoldings, a hail of stonework, rushing
and bounding through the dust and smoke on to the roofs below; whilst the
violence of the shock would threaten the whole of Montmartre, which, it
seemed likely, must stagger and sink in one huge mass of ruins!

However, Guillaume had again risen. The candle standing on the ground,
its flame shooting up, erect and slender, threw his huge shadow all over
the subterranean vault. Amidst the dense blackness the light looked like
some dismal stationary star. Guillaume drew near to it in order to see
what time it was by his watch. It proved to be five minutes past three.
So he had nearly another hour to wait. He was in no hurry, he wished to
carry out his design punctually, at the precise moment he had selected;
and he therefore sat down on a block of stone, and remained there without
moving, quiet and patient. The candle now cast its light upon his pale
face, upon his towering brow crowned with white hair, upon the whole of
his energetic countenance, which still looked handsome and you
