"That will just suit me," replied Ferris.

The two passed on. Hal raised himself from his cramped position, and made after them.

Once around the corner of Sixth Avenue, Hardwick led the way into an open hall-way, lit up with a single gas-jet. The pair commenced to ascend the stairs, which had several sharp turns. Hal was not far behind.

"I'll find out what they are up to, if I die for it," he said, and clenched his hands.

Several sentences were spoken which the youth did not catch, and then came a cry from Hardwick.

"What is that you say?" he demanded. "You saw this Carson just before you left your aunt's house?"

"Yes."

"Impossible!"

"Why should it be!" asked Ferris.

Hardwick did not reply.
