An hour later they entered the office of a famous shipping company in Cockspur Street, and there inquired for a boat sailing for the Dominion.

“There is the Argonaut. She sails from Liverpool in three days. I believe there are vacancies.” The clerk turned away and presently came back with a list in his hand.

“The accommodation is limited, I find. There are only a couple of cabins-de-luxe——”

“We will take them!” said Joy promptly.

“Thank you! What names, Miss?”

The names were given, and within ten minutes the transaction was completed, and Joy left the office with the tickets in her handbag. Just as her car started a taxi approached from the opposite direction, almost collided with it, and it was only by a decidedly dangerous swerve that an accident was averted. The taxi-driver glanced round at his passenger as if expecting a rebuke, but to his relief the man was leaning far back in the corner as if anxious to avoid observation. The vehicle drew up at the shipping offices, and the passenger left the taxi and entered the offices. He was Adrian Rayner.

The clerk who had completed Joy’s business attended to him and listened to his request.

“Sorry, sir! The last two cabins on the Argonaut have just been taken. There isn’t a vacant berth in the ship.”

Rayner considered. He had not the slightest doubt that Joy Gargrave and her foster-sister had taken those cabins, for he had seen them leaving the offices. A dark frown came on his face, which the clerk misinterpreted for disappointment. An idea occurred to him.
