“I did,” said Sanders and stopped.

Collins was quite at his ease. Sander’s fit of wild jealousy was passing away. “Lost it?” he said.

“Yes, I got rid of it,” said Sanders in some confusion.

“But we must not stay here; if you tell me on your word of honour it was not you I heard, I will apologize for my words.”

“Certainly I will, but it is to Miss Watson that an apology is due, not to me.”

“Of course I cannot mention it to her, she would never forgive me. And I hope you will not do so.”

Collins looked straight at him.

“I should advise you to keep these fits of excitement within bounds—and,” he added slowly, “when they do come on, to leave your revolver behind you.”

“What do you mean?” said Sanders, turning white.

“When you called on Sir James Watson and asked to see him, you were in one of those fits. It is dangerous.”
