"Yes," Toffee snickered wickedly. "But it isn't much fun. Did you have to knock them out so soon? I was only getting started."
"Never mind," Marc growled. "We've got to concentrate on getting to Herrigg. The entrance must be near here. Do you see a panel anywhere?"
"It's probably disguised," Toffee offered. "When that ape grabbed me, he just rubbed his hand over the wall to open the door. We might try rubbing this wall and see what happens. It may be an invisible beam that has to be broken at close range."
"Anything's worth a try," Marc answered, and accordingly, advanced to the wall and began running his hands swiftly in both directions.
For a time the little party clawed silently at the wall like a trio of demented sand crabs. It was doubtful that Harold really knew the purpose of this activity, but he joined in with great good will. Finally, their industry came to an end as Marc spoke:
"I think I've got it," he whispered. "There's a smooth spot over here."
Even as he spoke, a sudden flash of bright light fell over them as a slit appeared in the side of the cliff, to reveal the familiar dome-like room. Marc stole back for another look at the guards, and finding them still unconscious, returned swiftly to the door.
"Is Herrigg there?" he asked, approaching Toffee.
"I don't see him," Toffee answered. "I think the room's empty."
They crept forward. Toffee was right; the room was deserted. Removing his jacket, Marc moved into the passage again, and by hanging the garment on a jagged rock, managed to cover the smooth surface that opened the door.
