Can't you see?"

"Well, see that no harm comes to her--remember the arm of English law is long." Then Magra turned and walked back into the village.

After a sleepless night of searching for Helen, Gregory, Tarzan, and d'Arnot were gathered in Gregory's room to formulate their plans.

"I'm afraid there's nothing left to do but notify the authorities," said d'Arnot.

"I suppose you're right," agreed Gregory. "I was so afraid they'd kill her if we notified the police, but now there seems to be nothing else to do."

There was a knock at the door, and the three men looked up. "Come in!" said Gregory.

The door swung slowly open, and Magra stepped into the room.

"You!" exclaimed d'Arnot.

She paid no attention to him, but looked straight at Tarzan. "Brian Gregory," she said, "I have come to help you find your sister."

"What do you know about her? Where is she?" demanded Gregory.

"Atan Thome is taking her into the interior. He left for Bonga on the river boat last night."

"But the boat doesn't sail until today," interrupted d'Arnot.

"Atan Thome bribed the captain to sail last night," Magra explained. "I was to have gone, but--well, why I didn't is immaterial."

"This woman is not to be trusted," said Tarzan.

"You can trust me--always, Brian Gregory." She turned to Gregory. "If you doubt me, keep me with you--as a hostage, perhaps. It is possible that I may be able to help you."

Gregory appeared not to hear her. He seemed stunned. "Both my children," be said. "First Brian, now Helen, sacrificed--and for what?"

"Do not despair, Monsieur Gregory," said d'Arnot. "There must be a way."

"But how?" demanded the older man. "In four days Thome will be in Bonga. The boat will lie there at least one day. Coming back with the current, she will make the return trip in two and a half days, perhaps. Even if we can persuade the captain to return to Bonga immediately Thome will have had six or seven days start of us. He will be far into the interior. He probably has the map that was stolen from Helen's room. We have none. We will not know where to look for him."

"Do not worry on that score," urged d'Arnot. "If Thome is in Africa, Tarzan of the Apes will find him."

"Yes," agreed Gregory, dully, "but what will have happened to my poor girl in the mean time?"

"Wait!" exclaimed d'Arnot. "I have it! There is yet a way. We have a naval seaplane here. I'm sure the authorities will fly us to Bonga. We shall be there when Monseiur Thome lands. What a surprise for Monsieur Thome, eh?"

"Wonderful!" cried Gregory. "How can I ever thank you, Captain?"

Whatever her reaction, Magra's face showed no emotion.

Chapter 5

AT D'ARNOT'S REQUEST, the authorities were glad to co-operate; and with a delay of only a couple of hours the party was boarding a seaplane anchored in the river. Magra's expression suggested utmost self-satisfaction, as d'Arnot helped her aboard from the native canoe that had brought the party from shore. Wolff, who had never flown, swaggered a bit to hide Ms inward perturbation. Ogabi's eyes rolled fearfully.

"You see how easily everything was arranged?" exclaimed d'Arnot.

"Thanks to you," replied Gregory.

"How long will it take you to fly to Bonga, Lieutenant?" Tarzan asked the pilot.

"Between two and three hours," replied Lavac.

"It will take the steamer four days, against the current," said d'Arnot.
