mind instantly suggested a way by which the baronet could
be done to death, and yet it would be hardly possible to bring home the
guilt to the real murderer.

"Having conceived the idea he proceeded to carry it out with
considerable finesse. An ordinary schemer would have been content
to work with a savage hound. The use of artificial means to make the
creature diabolical was a flash of genius upon his part. The dog he
bought in London from Ross and Mangles, the dealers in Fulham Road. It
was the strongest and most savage in their possession. He brought it
down by the North Devon line and walked a great distance over the moor
so as to get it home without exciting any remarks. He had already on his
insect hunts learned to penetrate the Grimpen Mire, and so had found a
safe hiding-place for the creature. Here he kennelled it and waited his
chance.

"But it was some time coming. The old gentleman could not be decoyed
outside of his grounds at night. Several times Stapleton lurked about
with his hound, but without avail. It was during these fruitless quests
that he, or rather his ally, was seen by peasants, and that the legend

By representing himself as a single man he acquired complete influence
over her, and he gave her to understand that in the event of her
obtaining a divorce from her husband he would marry her. His plans were
suddenly brought to a head by his knowledge that Sir Charles was about
to leave the Hall on the advice of Dr. Mortimer, with whose opinion he
himself pretended to coincide. He must act at once, or his victim might
get beyond his power. He therefore put pressure upon Mrs. Lyons to
write this letter, imploring the old man to give her an interview on
the evening before his departure for London. He then, by a specious
argument, prevented her from going, and so had the cha
