Donatello sighed again, and led the way up into the tower.

Mounting the broad staircase that ascended from the entrance hall,
they traversed the great wilderness of a house, through some obscure
passages, and came to a low, ancient doorway. It admitted them to a
narrow turret stair which zigzagged upward, lighted in its progress by
loopholes and iron-barred windows. Reaching the top of the first flight,
the Count threw open a door of worm-eaten oak, and disclosed a chamber
that occupied the whole area of the tower. It was most pitiably forlorn
of aspect, with a brick-paved floor, bare holes through the massive
walls, grated with iron, instead of windows, and for furniture an
old stool, which increased the dreariness of the place tenfold, by
suggesting an idea of its having once been tenanted.

"This was a prisoner's cell in the old days," said Donatello; "the
white-bearded necromancer, of whom I told you, found out that a certain
famous monk was confined here, about five hundred years ago. He was a
very holy man, and was afterwards burned at the stake in the Grand-ducal
Square at Firenze. There have always been stories, Tomaso says, of
a hooded monk creeping up and down these stairs, or standing in the
doorway of this chamber. It must needs be the ghost of the ancient
prisoner. Do you believe in ghosts?"

"I can hardly tell," replied Kenyon; "on the whole, I think not."

"Neither do I," responded the Count; "for, if spirits ever come back,
I should surely have met one within these two months past. Ghosts never
rise! So much I know, and am glad to know it!"

Following the narrow staircase still higher, they came to another room
of similar size and equally forlorn, but inhabited by two personages of
a race which from time immemorial have held proprietorship and occupancy
in ruined towers. These were a pair of owls, who, being doubtless
acquainted with Donatello, showed little sign of alarm at the entrance
of visitors. They gave a dismal croak or two, and hopped aside into the
darkest corner, since it was not yet their hour to flap duskily abroad.

"They do not desert me, like my other feathered acquaintances," observed
the young Count, with a sad smile, alluding to the scene which Kenyon
had witnessed at the fountain-side. "When I was a wild, playful boy, the
owls did not love me half so well."

He made no further pause here, but led his friend up another flight of
steps--while, at every stage, the windows and
