fast enough. As for my crew, they knew too much about me, and it was time I was rid of them. It may be that Providence, acting through Black Lowther, has done me a good turn."
The thought seemed to amuse him. He smiled more broadly, then added thoughtfully:
"It happens that the four who are saved are very faithful dogs whom I can trust and use. Else it might be well to finish what Lowther and the ocean between them could not quite accomplish."
He paced to and fro on the beach, while Lachlan watched him in silence. Presently he halted and stood facing the younger man.
"I have a bargain to propose to you, Mr. McDonald," he said, "though why I bargain with you I hardly know. You are alone with me on a lonely shore. Man to man, you are not my match. I am heavier and stronger. You are weak from last night's ordeal. You are not fit either to fight or to run. I have no weapon, but I can easily kill you with my hands or with that piece of driftwood yonder.
"My proposal is this: You will forget what you learned in my cabin about my dealing with the Spaniards. You will forget, too, that you saw the black flag flying at my peak or that I am aught else than an honest privateersman. You will give me your word of honour that you will not use these things against me in any way."
He ceased abruptly and stood searching Lachlan's face.
