"Without doubt! There is no question of that in my mind."

Five minutes later the inquest stood adjourned, and those chiefly concerned gathered together in the emptying court to discuss the voluntary witness's evidence. Matherfield manifested an almost cheerful optimism.

"This is better!—much better," he declared, rubbing his hands as if in anticipation of laying them on something. "We know now that Hannaford met, at any rate, two men that night. It's easier to find two men than one!"

Rhona, whom Hetherwick had escorted to the coroner's court, looked her astonishment. "How can that be?" she asked.

"Mr. Hetherwick understands," answered Matherfield with a laugh. "He'll tell you."

But Hetherwick said nothing. He was always wondering—always wondering—about the woman whose picture lay in his pocket.

CHAPTER IV

THE DIAMOND NECKLACE

The conviction that there was more than met the eye in Hannaford's cutting out and putting away the handsome and distinguished woman's photograph grew mightily in Hetherwick's mind during the next few days. He recalled all that Hannaford had said about it in the train in those few short minutes before his sudden death. Why had he been so keen about showing it to the other man? Was he taking the other man specially to his hotel to show it to him—at that time of night? Why did the recollections which his possession of it brought up afford him—obviously—so much interest and, it seemed, amusement? And what, exactly, was meant by the pencilled words in the margin of the cutting?—Through my hands ten years ago! Under what circumstances had this woman been through Hannaford's hands? And who was she? The more he thought of it, the more Hetherwick was convinced that there was more importance in this matter than the police attached to it. They had proved utterly indifferent to Hetherwick's account of the conversation in the train—that, said Matherfield, with official superiority, was nothing but a bit of chat, reminiscence, recollection, on the ex-superintendent's part; old men, he said, were fond of talking about incidents of the past. The only significance Matherfield saw in it was that it seemed to argue that whoever the man who had disappeared was, he and Hannaford had known each other ten years ago.
