Of Hammond’s deputies, however, ten men were wounded by knives or bullets, and three had given their lives. Don Winslow and Red each bled from knife slashes received in the melee. The old lion, Michael Splendor, had taken a bullet through the throat, but he still lived by a miracle. Mercedes, with Lotus’ help, had just finished bandaging the veteran’s wound when Don located them back stage. Count Borg lay near by, conscious but unable to rise.

The problem now was to evacuate safely both walking persons and wounded. Don himself had just turned back to take charge when the little French maid, Suzette, appeared suddenly out of the shadows.

“Come with me, Monsieur,—you and two others!” she cried, seizing the young Commander’s arm. “I have locate Cho-San and Scorpion himself in their secret chamber. They are prepare now the getaway with their treasure and secret papers. In a few moments they will be gone!”

Red Pennington and Mercedes were near enough to overhear. Their response was instantaneous.

“We’re with you, Don!” they said, almost together.

“Hammond! Take charge of clearing out prisoners and wounded!” he ordered. “Get Mr. Splendor out first. We’ll see you topside.”

Before the Bureau Chief could answer Don turned, heading into the stage wing at Suzette’s heels. Mercedes and Red followed, stowing away their gas masks as they ran. If more fighting were ahead of them, they would need free hands and clear eyesight.

Suzette led them through a rapid succession of passageways and sliding panels, without stopping for explanations. Not until all four of them had crowded into a tiny elevator and shut the door, did she answer any of the questions in the others’ minds.

“We are now descending to the basement of Cho-San’s big house,” she whispered. “This is the way he escaped a few minutes ago. I guess where he have gone, and follow him by a roundabout way. I listen and hear him talk with the Scorpion in the secret chamber. Now if we are quick....”
