“According to the Prince there’s more treasure in his ancestral halls than we could cart away in a year. If Dr. Gaylord will help us we won’t lose anything by giving him his share.”

“I don’t see how he can help us a bit,” declared Archie. “For my part I’d rather have Ned Britton or Mr. Perkins. They’re true blue and game to fight to the last.”

“This isn’t a matter that depends on fighting, Archie,” I reminded him. “Our whole ship’s crew wouldn’t make a showing against the thousands of Chinamen if it came to open warfare. It’s a question of ready wit, courage and audacity.”

“Then I can’t make out why you want the doctor,” returned Archie, with a puzzled look.

“I know,” said Joe, in his quiet voice. “I think I’ve caught Sam’s idea, and it’s a good one.”

“What is it, then?” asked Archie.

“With the doctor’s help we can fool Mai Lo and save him from disgrace. And that will win his gratitude. Eh, Sam?”

“Quite right, Joe. Shall I call the doctor over?”

They nodded, and at my summons Dr. Gaylord willingly joined our little group.

“Doctor,” said I, “there’s a conspiracy afloat. Do you want to join it?”
