Kowen opened the door and bowed his visitor out. She held her head high, and there was an expression of indignation in her face. The sheriff watched her disappear into the hall, and then reached for his hat.
On second thought, Kowen had decided to shadow Mamie Blanchard himself, assisting his deputy. He gave Miss Blanchard time to reach the street, and then he started. She was already half a block away, making for the nearest department store, and Kowen saw his faithful deputy trailing her.
Mamie Blanchard, under the eyes of the sheriff and deputy, entered the store and began making purchases in an ordinary manner. Kowen approached the deputy and engaged him in low conversation.
"That's the girl that tipped me off about the gambling house," he said, "and I know blamed well that she belongs to the Black Star's gang. I tried to get some information out of her just now, but she's pretty wise. We'll keep out of her sight, work independently, and trail her. She may lead us to the big crook's headquarters."
Mamie Blanchard made purchases at several departments, and then left the store. If she was aware that she was under surveillance, she did not betray it by her actions. She visited a soda fountain and ate ice cream, emerged again, and finally engaged a taxicab. Sheriff Kowen engaged another, and his deputy a third.
They trailed her to a part of the city where were to be found houses that once had been the homes of wealthy persons of social prominence. But now those of wealth and society had moved to another section, and these relics of other days were rented for various purposes. Here were to be found small shops, cheap boarding houses, palmists, clairvoyants and others of their ilk. Here and there were smaller houses back from the street, some with billboards before them.
Mamie Blanchard left her taxicab at a corner, glanced around, and walked down the street. Kowen and the deputy shadowed her. It was not difficult in this section.
Mamie Blanchard was acting as if apprehensive now. She glanced around continually. Once she stood for several minutes in front of a store window.
"On the right track!" Sheriff Kowen told himself. "She's going to that crook's headquarters, all right, and she wants to make sure she isn't being followed."
He made a sign to his deputy, and they began to approach each other. Mamie Blanchard had walked on down the street. Suddenly she darted through a little gate, and walked swiftly toward one of the smaller houses that sat back from the street.
