Muggs never forgot that wild ride in the flivver. The street-car conductor drove the little machine as if it had been a racing car. It lurched around corners, almost ran down traffic policemen, swung ahead of street cars. The conductor was like a maniac. He always had craved excitement and adventure. Now it had come to him, and he intended to make the most of it.

They dashed up to the Branniton residence, and Muggs, not even thinking of thanking the conductor, sprang out and rushed across the lawn.

"Boss! boss!" he shrieked above the din.

Somebody told him that Verbeck was on the veranda. He rushed there and found his employer.

"Boss, was I in time?" he asked. "I got loose as soon as I could!"

"You bet you were, Muggs. The Black Star's inside, with some of his gang!"

"I told the big stiff this was goin' to be his unlucky night! You give me a chance to get at him, boss! I've got a few scores to settle with that bird!"

"We'll all get at him, Muggs! We'll be inside in a minute!"

The doors and windows were crashing in now. Policemen and deputies were pouring into the house. Shots greeted them, shots from both automatics and vapor guns. They struggled through clouds of the pungent vapor, here and there a man dropping because he had inhaled some of the fumes. They grappled with men in black robes and masks. Through the house they fought, while outside were others who watched every exit and caught those who tried to get away from the place.

One of the deputies had been an electrician formerly, and he knew where the light switches were located in the Branniton house. He fought his way to the kitchen, found them, and turned on the lights.

Things were better for the policemen and deputies after that. They could tell friends from foes. The Black Star's men barricaded themselves in certain rooms. Some of them threw down their weapons and held up their hands in token of surrender, and were immediately seized and handcuffed. The others were cleared from the lower floor, fought up the wide stairs, and continued the battle on the second floor.

Verbeck and Muggs were in the thick of the fight. They were looking for the Black Star. So were the chief, and Sheriff Kowen. They searched the basement and the rooms on the ground floor, but found no trace of him.

"He's on the second floor!" Verbeck cried. "Up we go!"

The guests who had been held prisoners were released from the room in which they had been locked. The women fled to the lawn, and across it to the street. Some of the men went with them; others joined in the fray. There was a crowd in the street now and more people were arriving every minute. Word had flashed throughout the city that the Black Star and his followers had been cornered in the residence of Richard Branniton.

The members of the band were being caught rapidly. A few had been wounded, a few officers also. But the criminals were scattered now, and here and there one surrendered, or was overpowered.

Verbeck and Muggs, the chief and the sheriff thought of nothing but the Black Star. They knew that the policemen and deputies could care for the others of the band. It was the master criminal himself that they wanted, to put him behind prison bars once more, to have years added to his sentence, to send him to the big prison up the river where he no longer would be a menace to society at large.

They ran from room to room, searching for him. They shrieked suggestions to one another above the din of the battle. They found a room at one end of the upper hall, with the door locked, and hurled themselves against it and broke it in.

There they saw the man they wanted. He had thrown off his robe and mask. He held a bomb in his hand—and stopped them with a gesture.

"Wait!" he commanded. "This is not a vapor bomb—it is the real thing. It can blow all of us to bits! So four of you came to get me, eh? Mr. Verbeck, and the chief and the sheriff—and Muggs. I suppose, since you are free and here, that you did all this, Muggs?"

"You bet I did!" Muggs cried.

"Wait, gentlemen! Don't make a move to raise a weapon, or we all will be hurled into the hereafter." The Black Star stepped back toward a window. "I suppose you have me cornered," he said. "I suppose you think you are going to take me back to jail. But it happens that I have one card yet to play!"

He hurled the bomb, and it exploded. It was a vapor bomb, after all. The cloud of pungent gas assailed them. They whirled to either side, away from it. There was a crash of glass.

"He's gone through the window!" Muggs shrieked.

Trying to keep from breathing, they rushed to the window, got through it and to the roof of the veranda, where they gulped the fresh air!

The Black Star had jumped to the ground. They saw him for an instant. Then he was lost in the darkness. The chief shouted a warning to his men.

"Down, and after him!" Verbeck cried.

"We've got him!" cried the chief. "The entire yard is surrounded. He's in a trap!"

Muggs was the first to reach the ground. He did not stop to climb down one of the posts, but did as the master criminal had done—jumped.

Verbeck and the chief and Sheriff Kowen were not far behind him. Officers who had been on the veranda charged after the Black Star in response to the chief's command.

The net grew tighter. They were in a corner of the lawn, calling to one another. A police auto drove across the grass, and the searchlight was turned on.

There was the circle of policemen and deputies, with Verbeck and Muggs, the chief and the sheriff at one side of it.

But the Black Star was gone!
