Without further opposition they boarded the yacht, which there was no longer reason to doubt was the Halcyon.

As they gained the deck, some figures darted along it and vanished.

Headed by Ned and Herc, three of the men dashed after them. The rest were left to guard the deck.

"That was Kenworth and Saki," gasped Herc as they rushed down the companionway stairs and into the main saloon of the yacht.

Ned nodded grimly.

"We've rounded them up at last," he said drawing his revolver and ordering Herc to do the same.

Slam!

Just as they gained the saloon, the door of a stateroom opening from it was banged to. An instant later came the click of a bolt as it was shot.

"Open that door, Kenworth," cried Ned with perfect coolness. "You're at the end of your rope."
