She was wondering whether Walter Fetherston had guessed the truth, that she had loved that man who had met with such an untimely end.

Her companion, on his part, was equally puzzled. That story of Barker's finding a white feather was a curious one. It was true that the man had found a white feather—but he had also learnt that when Enid Orlebar had arrived at Hill Street she had been wearing a white feather boa!

"It is not curious, after all," he said reflectively, "that the police should have dismissed the affair as a death from natural causes. At the inquest no suspicion whatever was aroused. I wonder why Barker, in his evidence, made no mention of that perfume—or of the discovery of the feather?"

And as he uttered those words he fixed his grave eyes upon her, watching her countenance intently.

"Well," she replied, after a moment's hesitation, "if he had it would have proved nothing, would it? If the captain had received a lady visitor in secret that afternoon it might have had no connection with the circumstances of his death six hours later."

"And yet it might," Fetherston remarked. "What more natural than that the lady who visited him clandestinely—for Barker had, no doubt, been sent out of the way on purpose that he should not see her—should have dined with him later?"

The girl moved uneasily, tapping the ground with her stick.

"Then you suspect some woman of having had a hand in his death?" she exclaimed in a changed voice, her eyes again cast upon the ground.

"I do not know sufficient of the details to entertain any distinct suspicion," he replied. "I regard the affair as a mystery, and in mysteries I am always interested."

"You intend to bring the facts into a book," she remarked. "Ah! I see."
