"Well, come along," said Sharp, smiling grimly, "we shall find out
before long."

They soon reached the scene of the robbery, and were able to examine the
place by the light of the moon, which had just managed to pierce the
thick veil of clouds that had covered it during the earlier part of that
night. Then they retired to a shady cavern, or hole, or hollow at the
foot of the embankment, near to the gap in the hedge, and there they
prepared to pass the night, with a heap of mingled clods and stones for
their couch, and an overhanging bank of nettles for their canopy.

It was a long weary watch that began. There these patient men sat, hour
after hour, gazing at the moon and stars till they almost fell asleep,
and then entering into animated, though softly uttered, conversation
until they roused themselves up. It was strange converse too, about
struggles and fights with criminals and the detection of crime. But it
was not _all_ on such subjects. No, they forsook the professional path

The satellite, thus set free, went home and set immediately--in his bed.
The luminary himself postponed his setting for a time, put the thief's
shoe in his pocket and went straight to the residence of Bill Jones,
which he reached shortly after the grey dawn had appeared. Here he
found Bill in bed; but being peremptory in his demand for admission,
Bill arose and let him in.

"You look rather pale this morning, Bill?"

"Bin at work late, sir," said Bill uneasily, observing that the
superintendent was casting an earnest glance all round his room.

Jones was a bachelor, so there wasn't much of any kind to look at in the
room.

"You've been treating yourself to a new pair of shoes, I see, Jones,
what have you done with the old ones?"

"I--they're wo
