“Flannagan!” he exclaimed.

The detective was tugging at his revolver, which had stuck in his hip pocket.  Byrne reached for his own weapon.  Bridge laid a hand on his arm.

“Not that, Billy!” he cried.  “There’s a door behind you.  Here,” and he pulled Billy backward toward the doorway in the wall behind them.

Byrne still clung to his schooner of beer, which he had transferred to his left hand as he sought to draw his gun.  Flannagan was close to them.  Bridge opened the door and strove to pull Billy through; but the latter hesitated just an instant, for he saw that it would be impossible to close and bar the door, provided it had a bar, before Flannagan would be against it with his great shoulders.

The policeman was still struggling to disentangle his revolver from the lining of his pocket.  He was bellowing like a bull—­yelling at Billy that he was under arrest.  Men at the tables were on their feet.  Those at the bar had turned around as Flannagan started to run across the floor.  Now some of them were moving in the direction of the detective and his prey, but whether from curiosity or with sinister intentions it is difficult to say.

One thing, however, is certain—­if all the love that was felt for policemen in general by the men in that room could have been combined in a single individual it still scarcely would have constituted a grand passion.

Flannagan felt rather than saw that others were closing in on him, and then, fortunately for himself, he thought, he managed to draw his weapon.  It was just as Billy was fading through the doorway into the room beyond.  He saw the revolver gleam in the policeman’s hand and then it became evident why Billy had clung so tenaciously to his schooner of beer.  Left-handed and hurriedly he threw it; but even Flannagan must have been constrained to admit that it was a good shot.  It struck the detective directly in the midst of his features, gave him a nasty cut on the cheek as it broke and filled his eyes full of beer—­and beer never was intended as an eye wash.

Spluttering and cursing, Flannagan came to a sudden stop, and when he had wiped the beer from his eyes he found that Billy Byrne had passed through the doorway and closed the door after him.

The room in which Billy and Bridge found themselves was a small one in the center of which was a large round table at which were gathered a half-dozen men at poker.  Above the table swung a single arc lamp, casting a garish light upon the players beneath.

Billy looked quickly about for another exit, only to find that besides the doorway through which he had entered there was but a single aperture in the four walls-a small window, heavily barred.  The place was a veritable trap.

At their hurried entrance the men had ceased their play, and one or two had risen in profane questioning and protest.  Billy ignored them.  He was standing with his shoulder against the door trying to secure it against the detective without; but there was neither bolt nor bar.
