nly heard. The next moment
a key turned in the lock of the door, which was silently shoved inward.

The visitor, whoever he was, acted with the coolness of a professional. He
entered by the main door, so, if it chanced that any one saw him, he could
explain the cause of his visit. At the same time, he made as sure as was
possible that no one did see him. Knowing the movements of the watchman,
he waited until he was out of the way, with the certainty that he would
not be back again under a half-hour at the least. That interval was more
than sufficient to do all that he had in mind, and to take his departure.

He opened the door so quietly that, but for the warning rattle of the key,
it would have been hard for the watchers to hear him. Almost before they
knew it he stood inside with the door closed. Here the light fell upon

Neither was surprised. Although they had not mentioned their suspicions to

more like the exquisite on the steamboat than did Tom Gordon himself. He
was the sleek, cunning, hypocritical villain he had always been, stealing,
not because he was in need of money, but because it was his nature to do
so.

"_Well, Mr. Catherwood, it looks as if the account will be a little short
to-morrow_!"

The miscreant started as if he had heard the warning of a rattlesnake at
his feet. Turning like a flash, he saw Mr. Warmore standing at his elbow.
Had he received but a few seconds' notice, he might have tried to bluff it
out, by pretending he had come to look after some matters about which he
was not fully satisfied. Holding the situation he did in the
establishment, he could feel certain no one would suspect him of any
sinister purpose.

But the exposure d
