"I only know," said Chick, "that he is said to keep one of the worst dives in the city, and that it is located somewhere in Rivington Street. I am not sure about it, because I have never had occasion to go there. The only thing I do know about it is that it is said to be a great Sunday night resort for thieves and crooks of all classes."

"Right," said Nick. "That coincides with what I have heard. I have never been there, either, Chick but I am going there to-night—now. The question is, do you want to go with me?"

"I sure do," replied Chick.

CHAPTER XXI.

CURLY JOHN, THE BANK THIEF.

Mike Grinnel's place in Rivington Street was at that time one of those monstrosities which were permitted to exist within the limits of New York City nobody knows how. During the day and the early part of the evening it was to all appearances merely an ordinary saloon, and if a stranger were passing it he would regard it as a likely place to enter if he required refreshment.

But when the hours deepened into the night, the place gradually assumed more and more the aspect which might be labeled dangerous. Men and women drifted in together and talked in low tones at tables arranged along the side of the room, and as the time continued toward midnight, and passed it, the air of respectability gradually disappeared until it was entirely gone.

By eleven o'clock the place was usually thronged by people who seemed to know each other in a furtive sort of way, and who sometimes would call others by name across the room.

At one o'clock the front doors were closed and locked; the curtains were tightly drawn so that not a ray of light was permitted to escape into the street, blinds were pulled up to make this fact doubly secure, and this was when the place really began to live and thrive in its true character. Then also was when Mike Grinnel himself came out of his shell, and assumed personal charge of the affairs of the place; for Mike Grinnel had a reputation among the crooks and thieves who were his customers, and if an incipient row started at any time among his guests he had only to look with his frowning brow in their direction to quell it.
