“Ah, you think so?” cried Sir Arthur. “Bless me, I hope we will. I have an engagement to dine with Lord Balsover at the Hotel Bombay at Aden on the 10th at six o’clock in the evening. He touches there on his way to India, and I can’t disappoint him, you know.”

“Drop him a few lines, Ashby, and postpone the engagement a couple of weeks,” remarked the colonel dryly.

“Bless me! Can I do that?” ejaculated Sir Arthur.

“Get on board,” directed Guy, setting the example himself, and assisting Bildad.

“Let go, Forbes,” said Guy in a firm voice.
