"Is he playing us false—has he escaped to save himself?"
"No," said Mr. Kenyon firmly, "but speak lower. Sound travels along the river by night."
"Sree would not cheat us, Mr. Cameron," said Harry bitterly. "I'll answer for him."
"Then why doesn't he return—why doesn't he return?"
"Because he has much to do."
"But he must have been three hours away," said the doctor excitedly. "I cannot bear this inaction longer. Kenyon, you must have me put ashore yonder."
"No," said Harry's father sternly; "I must take the lead here, for all our sakes. The man has his life to look to, and has no doubt had to thread his way among enemies."
"He will not come back," said the doctor. "I will wait another half-hour, and then at all costs I will be set ashore."
"Be silent, please," said Mr. Kenyon sternly.
"Ah, there he is," whispered Harry, for there was a low, hoarse, piping cry from the opposite bank.
