of money, he could not understand anyone simulating such an emotion
except for show intended to deceive. He thought that she had come to
Castra Regis again for the opportunity of stealing something, and was
determined that on this occasion the chance of pressing his advantage
over her should not pass. He felt, therefore, that the occasion was one
for extra carefulness in the watching of all that went on. Ever since he
had come to the conclusion that Lady Arabella was trying to steal the
treasure-chest, he suspected nearly everyone of the same design, and made
it a point to watch all suspicious persons and places. As Adam was
engaged on his own researches regarding Lady Arabella, it was only
natural that there should be some crossing of each other's tracks. This
is what did actually happen.

Adam had gone for an early morning survey of the place in which he was
interested, taking with him the mongoose in its box. He arrived at the
gate of Diana's Grove just as Lady Arabella was preparing to set out for
Castra Regis on what she considered her mission of comfort. Seeing Adam
from her window going through the shadows of the trees round the gate,
she thought that he must be engaged on some purpose similar to her own.
So, quickly making her toilet, she quietly left the house, and, taking
advantage of every shadow and substance which could hide her, followed
him on his walk.

Oolanga, the experienced tracker, followed her, but succeeded in hiding
his movements better than she did. He saw that Adam had on his shoulder
a mysterious box, which he took to contain something valuable. Seeing
that Lady Arabella was secretly following Adam, he was confirmed in this
idea. His mind--such as it was--was fixed on her trying to steal, and he
credited her at once with making use of this new opportunity.
