He was in the manufacturing district, he knew. This building was an old, abandoned factory. He could see the yard filled with scrap iron, the high fence around it, and, beyond, the empty street. Farther beyond that was the city, flashing with light.

Muggs started to raise the window. It stuck, but he managed to pry it up with the bar of iron, stopping now and then to listen and watch. He couldn't convince himself that the Black Star had left no guard other than the servant now unconscious below. That wasn't at all like the Black Star, Muggs thought. There must be a trap somewhere.

Then he remembered that the Black Star had been forced to move quickly. Perhaps this headquarters had not been completed when the master criminal had taken up his abode there.

Muggs got the window up, put out his head and looked around. It was pitch dark beneath the window and along the wall. Muggs got through, lowered himself and dropped.

He crouched against the wall, listening, the bar of iron clutched in his hand, ready for instant fight if occasion demanded it. Then he started following the wall, going toward where he had noticed a gate in the high fence.

He reached the corner of the building, and glanced around it cautiously. Not far from him, he seemed to see something move. Muggs was not sure at first whether it was an elusive shadow or a man. He decided an instant later that it was a man.

He scarcely breathed now. He had escaped thus far, and he did not intend to be stopped. He did not intend to waste much time, either. Even now, perhaps, the Black Star and his followers were surrounding the Branniton residence. Even now, perhaps, they were robbing women of their jewels, rendering the three men they had decided to abduct unconscious, and preparing to carry them away.

Like a shadow, the iron bar held ready, Muggs crept along the wall in the direction of the guard.

He was within ten feet of him when a match glowed. The flame shot up, and Muggs could see that the match was burning in the man's cupped hands, and that he was trying to light a cigar. Muggs covered the ten feet in two springs, the iron bar swept through the air and landed. There was a little whimper, and the Black Star's guard was stretched on the ground.

Muggs turned and ran across the yard. He had decided not to try the gate, for there might be another guard there. He sprang, grasped the top of the fence, running the risk that it might be charged and deadly, found that such was not the case, and drew himself up. A moment later, he was in the street.
