and excitement.

"I will detail a squad of men to go with you," said the chief. "Go at
once. No time is to be lost."

In less than an hour from the time Jack left the haunt of the coiners,
an authoritative knock was heard at the door.

It was answered by Foley.

The old man turned pale as he set eyes on Jack and the police, and
comprehended the object of the visit.

"What do you want, gentlemen?" he asked.

"Is that the man?" asked the sergeant of Jack.

"Yes."

"Secure him."

"I know him," said Foley, with a glance of hatred directed at Jack.
"He's a thief. He's been in my employ, but he's run away with fifty
dollars belonging to me."

"I don't care about stealing the kind of money you deal in," said Jack,
coolly. "It's all a lie this man tells you."

"Why do you arrest me?" said Foley. "It's an outrage. You have no right
to enter my house like this."

"What is your business?" demanded the police sergeant.

"I'm a physician."

"If you are telling the truth, no harm will be done you. Meanwhile, we

"I'll show you," answered Jack.

He showed the way upstairs.

"How did you get out?" he asked Foley, as he touched the spring, and the
secret door flew open.

"Curse you!" exclaimed Foley, darting a look of hatred and malignity at
him. "I wish I had you in my power once more. I treated you too well."

We need not follow the police in their search. The discoveries which
they made were ample to secure the conviction of the gang who made this
house the place of their operations. To anticipate a little, we may say
that Foley was sentenced to imprisonment for a term of years, and his
subordinates to a term less prolonged. The reader will also be glad to
know that to our hero was awarded the prize of a thousand dollars which
had been offered for the apprehension of the gang of counterfeiters.

But there was another notable capture made that day.

Mrs. Hardwick was accustomed to make visits to Foley to secure false
bills, and to make settlement for what she had succeeded in passing off.

While Jack and the officers were in the house she rang the door bell.

Jack went to the door.

"How is this?" she asked.

"Oh," said Jack, "it's all right. Come in. I've gone into the business,
too."

Mrs. Hardwick entered. No sooner was she inside than Jack closed the
door.

"What are you doing?" she demanded, suspiciously. "Let me out."

But Jack was sta
