The detective engaged in the game. He was not a gambler—he abhorred gambling. He had seen so many men drop down to poverty who had taken their first step back in a gambling den, and during the course of his career he had warned, and in some instances saved young clerks who were just beginning to slide downward. Gambling is a fatal amusement and sooner or later leads to disaster. Oscar, however, knew how to gamble. He had learned the various games merely as aids in his profession, for most criminals are inveterate gamblers, and it is in gambling dens where detectives find their richest fields for "dead shadows."

A few moments after Oscar had gotten into the game one of the men who were shadowing him also got in. It proved to be a very commonplace play. No large bets were made, no great sums were lost or won. The shadower had managed to crowd in beside our hero, and Oscar had favored him in securing the seat, and as was expected the man opened a conversation.

"A slow game," he said.

"Very," answered our hero laconically.

"I don't like this faro anyhow," said the man.

"It passes time."

"I prefer a good game of draw."

Oscar detected that the man was just playing a good game of draw—he was trying to draw our hero into a private little game of draw-poker; but it was not the poker that he wanted to inaugurate. His game was to draw our hero to some convenient place where he could play a still more significant game of draw.

"I like a game of draw myself," said Oscar, nowise loath to favor the man's game.

The detective did not know where it was all leading to, or what it was leading up to as a final denouement, but he was inured to the taking of desperate chances. Peril was a pastime to him. He was ever watchful and always prepared for danger.
