chard nor anything that would indicate that the cottage was a den of thieves. They located a trap door, and opened it, and saw a flight of steps running down into a dark basement.
"Careful!" Kowen warned his men. "They're probably down there waiting for us! We'll not all run into the trap!"
He delegated one man to remain above. He flashed his electric torch, but could see nothing except the flight of steps and the landing at the bottom. With some of the others close behind him, with his electric torch in one hand and his revolver in the other, Sheriff Kowen started to descend the steps.
Each instant they expected to hear the sound of a shot, or the explosion of a vapor bomb, or to encounter one of the traps rumor said the Black Star always had in his headquarters. Step by step they descended, but nothing happened.
They reached the landing, peered around the corner of a concrete projection. Sheriff Kowen gasped.
"Careful!" he warned again. "This is the headquarters, all right, and there doesn't seem to be anybody here—but you never can tell. Watch out for tricks and traps! Be careful what you touch and where you step. When he was after the Black Star before, Roger Verbeck found himself in a trap when he thought he was boss of the situation—don't forget that!"
The sheriff stepped to the floor, walked a couple of paces away from the steps. He saw an electric switch on the wall, hesitated a moment, and then turned it. The basement was bathed in light.
All the deputies with him were on the floor of the basement now. A chorus of gasps escaped them.
