"Thanks, mynheer," said Waynsford. "I'll wish you good-night. Sorry to have caused you any inconvenience.
"Der vas no drouble at all," rejoined the Dutchman. "Goot-night to you."
The sub descended the side and gained the cockpit of the "Lonette." The rope was cast off and the motor-boat slipped astern. Not one word did Waynsford say until the little craft was out of hearing distance, then—
"Where's Mr. Aubyn? he asked.
"Aboard yonder packet, sir," replied the member of the crew who had been left in charge of the motorboat. "He asked me to drop a few feet astern and then he slipped up over the Dutchman's quarter. Shall I give a hail, sir?"
"No," replied Waynsford. "Easy ahead."
