He turned, and saw that it was Tambourine Jack.

Crackers was with him.

“I want to tell you a hull lot, Mister Carter,” said Jack.

“I have no time to listen to you,” said the detective. “Do you see that woman ahead, in the long sealskin coat and the red hat?”

“Yes.”

“Well, I want you to follow her and come back and tell me where she stops,” commanded Nick. “She has looked back several times, and I am afraid she recognizes me.”

“I know the lady; we have met before,” said Jack. “She is a friend of Elmer Greer.”

The detective gave the little fellow money in case he should be obliged to take the cars.

“Hurry after her, and don’t lose her,” the detective said. “I will wait for you in that drug store on the corner.”

Tambourine Jack, after first turning Crackers over to Nick, hastened after Louise Calhoun.
