Nick said nothing, but left headquarters. He was disgusted, but he was still determined to find the banker.

He sauntered up Sixth Avenue and saw a lady whom he thought he recognized enter a dry-goods store on the corner of Fourteenth Street.

Nick followed.

She was for a moment lost sight of in the throng, but he again found her.

It was the woman who had attempted his life, Louise Calhoun!

CHAPTER VI.
A DANGEROUS WOMAN.

Nick Carter kept Louise Calhoun in sight, and when she left the store he followed.

She walked down Fourteenth Street to Eighth Avenue, and turned up that thoroughfare.

At the corner of Twenty-eighth Street the detective heard some one call him.
