They knew her at the first glance and their faces hardened.

“Clay’s lost no time,” Bethune remarked. “Well, I suppose it means a fight, and we’ll gain nothing by running away now, but we may as well stop diving until we find out whether it’s worth while to go on.”

After securing the pumps and gear they waited, watching the yacht’s approach. She came straight on at moderate speed, and stopped three or four hundred yards away. They saw the anchor splash and heard a rattle of chain, but after that there was no sign of activity on board the vessel.

“It’s my opinion Clay knows who we are,” Moran said.

“You can take that for granted,” Bethune replied. “We’ll hear from him before long, but he doesn’t mean to show any eagerness in sending a boat off. As time’s getting on, I think we’ll have supper.”

As they finished the meal a smart gig, pulled by uniformed seamen, approached the sloop, and when she stopped alongside the helmsman handed Jimmy two notes.

Opening them in the cabin, he showed his companions two sheets of fine paper bearing an embossed flag and the vessel’s name. One note stated that Mr. Clay requested their company at supper on board his yacht, and the other, which was longer, was from Aynsley. He said that although he was not sure they had much cause to remember him with gratitude, he would be glad to see them, and hoped they would not refuse his father’s invitation.

“Do you think Clay made him write this?” Jimmy asked.

“No,” said Bethune. “On the whole, I imagine it was sent without Clay’s knowledge. Of course, Aynsley had some reason for writing, but while I can’t tell what it is, he’s not in the plot.”

“Anyway, I’m not going; I’ve no wish to sit at that man’s table.”
