"Well, well, it don't matter, sir," said the captain. "Bill Brisket must put up with it. It's the first time in his life he's been suspected, and it's doubly hard coming from you. You've hurt me, sir, and there's no other man living could do that."

Mr. Chalk stood by in sorrowful perplexity.

"And I put my life in your hands," continued the captain, with a low, hard laugh. "You're the only man in the world that knows who killed Smiling Peter in San Francisco, and I told you. Well, well!"

"But you did it in self-defence," said the other, eagerly.

"What does that matter?" said the captain, turning and walking forward, followed by the anxious Mr. Chalk. "I've got no proof of it. Open your mouth—once—and I swing for it. That's the extent of my trust in you."

Mr. Chalk, much affected, swore a few sailorly oaths as to what he wished might happen to him if he ever betrayed the other's confidence.

"Yes," said the captain, mournfully, "that's all very well; but you can't trust me in a smaller matter, however much I swear to keep it secret. And it's weighing on me in another way: I believe the crew have got an inkling of something, and here am I, master of the ship, responsible for all your lives, kept in ignorance."

"The crew!" ejaculated the startled Mr. Chalk.

Captain Brisket hesitated and lowered his voice. "The other night I came on deck for a look round and saw one of them peeping down through your skylight," he said, slowly. "I sent him below, and after he'd gone I looked down and saw you and Mr. Tredgold and Stobell all bending over a paper."

Mr. Chalk, deep in thought, paced up and down in silence.
