Floyd watched the boat draw off and the oars making rings on the star-spangled water; then he returned to the cabin, where he found Cardon released from his prison and seated at the table.
"He's gone," said Floyd.
"And no sign of Luckman?"
"Not a sign."
"Well," said Cardon, "it's beyond me. However, we're not out of Sydney harbor yet, and there's no knowing what may happen before we are."
CHAPTER XXX
THE OPEN SEA
Floyd did not take the trouble to speak to Mountain Joe about Cardon's presence on board.
Cardon got into the upper bunk at about eleven o'clock and went promptly to sleep. As for Floyd, he could neither sleep nor lie still. During his stay in Sydney, he had been restless enough at times, but he had never felt like this. Ever since his departure from the island the idea of Isbel had followed him and been with him now clear and close, now more remote and partly obscured from him by everyday affairs.
