"Cinch!" said one of the five. "Let's go!"
"I'll have the other stuff ready," the baker informed them.
He opened the door and glanced into the other room, closed the door again and motioned that everything was all right. The five men hurried to the other end of the room, and one of them pressed against the wall. A small door swung open.
They passed through the wall and into the basement of the building adjoining. An engineer was asleep in a chair before his table, and he was rendered unconscious immediately by means of a vapor gun. The five hurried up a flight of stairs, opened a door, and entered a rear hall.
They were at the back of a famous jewelry establishment now, one that had a famous name in the business world, one which scorned to move to better quarters, but which was protected by every known device. Another door was opened, and they were in a storeroom.
They moved with more caution now, for this was dangerous ground. The Black Star had planned this attack on the assumption that he would be expected to rob a more pretentious establishment. Few men knew that a large shipment of gorgeous diamonds had recently been received by this firm—but the Black Star knew it. One of his band was a trusted clerk in the house.
Moreover, at that moment, the Black Star was creating a diversion. In the principal retail district of the city there was a fashionable jewelry store housed in a modern building. It was being heavily guarded this night, for the proprietors had taken cognizance of the master crook's announcement that he intended to purloin rare jewels, and they flattered themselves that their establishment would be the one visited.
More than a score of special watchmen and police officers were in this building. One of the proprietors himself was on hand, aiding in safe-guarding the jewels. The entire establishment was brilliantly lighted. The shades and fire curtains at the windows were raised, and the door of the vault room stood open so that it could be seen from the front street. The Pioneer Diamond Company was taking no chances of being looted.
And suddenly the building that housed the diamond company was bathed in brilliant light that seemed to come out of the sky! People in the streets, remembering what had happened three nights before, began shrieking that the Black Star and his men were at work. An alarm was sent to police headquarters, and relayed to the chief at the museum. The Black Star was robbing the Pioneer Diamond Company!
Leaving a small police guard at the museum, the chief hurried to the scene with the remainder of his men. Verbeck and Muggs went ahead in the roadster, charging through the streets, the horn shrieking a warning. As they arrived, the bright light had disappeared, but soon they saw it again.
