approach of
footsteps. He gathered his strength and bags and flung along, somewhat
refreshed by the change of burdens. As he made a turn, the fresh
outside air blew upon him. He grew cautious and moved more slowly,
listening now in both directions. He might not be overtaken, but some
one might be at the opening of the passage. There was no light or
sound beyond, and soon he stood in the deep darkness of the outer
night 'neath dripping trees. Warily he stepped, lest some cracking
twig exposed his presence.

He ascertained his surrounding was a thicket, and was about to make
his way into its labyrinthine density, step by step; for the way
was difficult, when there was a tramping of horses' hoofs upon the
rain-soaked road that appeared to be in close proximity.

Under cover of the noise he swept hastily and boldly through the
briery bushes that were thickly entangled, and was able to make
considerable headway whence he had come, when the noise ceased and a
peculiar whistle rang out; then there were a few moments of quiet, as
if those who signalled were listening for an answer.

There appeared to be a chaise with several outriders, as Buckingham
thought, by the tramp of horses' feet, and a creaking of wheels
pulling heavily along.

As he gazed anxiously in their direction, a torch was suddenly set

passage. He leant from his steed and examined the ground closely,
noting doubtless the footprints that led away from the road and
directly to the place where the Duke stood. He turned abruptly back to
the group upon the highway and conversed in low tones.

Buckingham was not a little perturbed, for a horseman could with less
trouble than it takes to tell it, track and overtake him in a moment's
time. He fain would have a few minutes to ease his burden, but his
peril was great. There was no doubt but what these men were monks,
come to assist their fellows with the chest and convey them to a place
of safety.

Indeed, the secret of the chest must be royal, but whether in jewels
or papers he did not know, nor was it the time and place to find out.
If he only knew in which pack was the bone of contention he would
certainly lighten his burden.

Again he lifted the bags and strode on lightly, for he still could be
heard to the highway, if one should listen.

He had not gone far, however, when there was a shout from the
subterranean opening and much confusio
