I'm goin' to have my half."

"You can do something more to help me," said Thome, "that will also make the diamond safer for us."

"What's that?" asked Wolff, suspiciously.

"I'm going to have Magra try to go along with the Gregorys. You may be able to help in that. I want her to make friends with them--and make love to Brian Gregory; then if anything goes wrong she'll have some influence with them. I don't want to hang, and neither do you."

"Where do I come in?" asked Wolff.

"You go along and lead them off onto a wrong trail. When they're good and lost, bring Magra up toward Ashair. You've seen the map; so you'll know about where to go. You'll find one of my old camps and wait there for me. Do you understand?"

"Yes."

"And you'll do it?"

"Sure. Why not?"

"All right. Now go along. I'll be seeing you up around Ashair in a couple of months."

After Wolff had left, Thome turned to Lal Taask. "We've got to get out of here tonight," he said. "Go down to the river and bribe the captain of that boat to get up steam and leave for Bonga tonight."

"You are very clever, Master," said Lal Taask. "You will let the young lady go, now that you have the map?"

"No. They didn't give me the map. They may catch up with us; and if they do, it will be just as well to have a hostage."

"Again, Master--you are clever."

It was past midnight when Atan Thome went aboard the river steamer with Lal Taask and Helen. At the gangplank he bid Magra goodby. "Join the Gregory safari by any ruse," he directed. "They may reach Ashair, and I want some one with them I can trust. I must be prepared for any eventuality. If they should beat me to it and get the diamond, you must find some way to communicate with me. You may even get an opportunity to steal the diamond. Watch Wolff. I don't trust him. He has agreed to lead them astray and then bring you up toward Ashair to meet me when I come out. It's a good thing you're in love with Brian Gregory. That will help. Work it for all its worth. I didn't like the idea at first; but when I got to thinking about it, I saw where we could make use of it. Now, goodby; and remember all I have told you."

Taask and Helen had boarded the steamer, the man walking very close to the girl, his pistol pressed against her side, lest she make an outcry.

"I think you are very foolish not to set her free," said Magra.

"I can't now," replied Thome--"not until after you have left the Gregory party.
