the place; and finding the iron bound
coffer and hearing the chink of coin within, they attacked it savagely
and succeeded in smashing the lock.

The sight of gold was too much for them. They scrambled, they fought,
they trampled upon each other. The yellow metal acted upon them like
strong drink. In the midst of the pandemonium came a deafening
explosion, a vivid flash of red, a volume of acrid suffocating vapour.
Another explosion and men came rushing from Mountchance's
laboratory--terror written in their faces. Helter-skelter the crowd
darted from the house forcing Sally Salisbury with them whether she
would or not. In the mad fight for gold large glass bottles filled with
acids, alcohol and other inflammable liquids had been upset and smashed,
and the smouldering fire in the furnace did the rest. What with the
bundles of dried herbs which burnt like so much tinder and the woodwork,
the panelled walls and furniture, nothing could save the house.

In the hurry and scramble Sally had been wedged against the wall
surmounting the central and largest arch. Upon this arch no house had
been built. Below the spot where she was held a prisoner the river was
rushing with its monotonous roar as if rejoicing at or indifferent to
the terrible tragedy above. At first she saw nothing but clouds of
suffocating smoke pouring from the windows, then showers of sparks
floating downwards and vanishing in the water, and finally tongues of
fire hissing and roaring from within the house and mingling in one huge
flaring flame.

Looking over the parapet she caught sight of a gaunt figure on the
abutment now strongly illuminated, now in deep shadow according to the
height and strength of the flames and the wayward wind. So fantastic, so
grotesque was this figure, his gesticulations, his waving hands, he
suggested a demon rather than a human being. Now and again he put a
curved hand to his mouth. Doubtless he was shouting but the roar of the
fire and the howling of the mob smothered every sound.

It was Rofflash--his true character revealed, nerve stricken, a coward
at heart. Yet he was in no immediate danger. The fire could not reach
him. The only thing he had to fear was the rising tide should it chance
to wash over the abutment and sweep him off his feet.

But it is always the unexpected that happens. Some receptacle with
inflammable contents which the fire had overlooked--probably it was
stored in one of the upper rooms--exploded with
