"Do you wish to summon any witnesses, Mr. Royce?" asked the coroner again. "I shall be glad to adjourn the hearing until to-morrow if you do."

Mr. Royce roused himself with an effort.

"Thank you, sir," he said. "I may ask you to do that later on. Just at present, I wish to recall Mr. Rogers."

"Very well," said the coroner, and Rogers was summoned from the witness room.

I looked at him attentively, trying to fathom his thoughts, to read behind his eyes; but look as I might, I could see nothing in his face save concern and grief. He had grown gray in Holladay's office; he had proved himself, a hundred times, a man to be relied on; he had every reason to feel affection and gratitude toward his employer, and I was certain that he felt both; he received a liberal salary, I knew, and was comfortably well-to-do.

That he himself could have committed the crime or been concerned in it in any way was absolutely unthinkable. Yet why should he lie? Above all, why should he seek to implicate his employer's daughter? Even if he wished to implicate her, how could he have known the color of her gown? What dark, intricate problem was this that confronted us?

In the moment that followed, I saw that Mr. Royce was studying him, too, was straining to find a ray of light for guidance. If we failed now——

I read the note through again—"a gown of dark green"—and suddenly, by a kind of clairvoyance, the solution of the mystery leaped forth from it. I leaned over to my chief, trembling with eagerness.

"Mr. Royce," I whispered hoarsely, "I believe I've solved the puzzle. Hold Rogers on the stand a few moments until I get back."

He looked up at me astonished; then nodded, as I seized my hat, and pushed my way through the crowd. Once outside the building, I ran to the nearest dry-goods house—three blocks away it was, and what fearfully long blocks they seemed!—then back again to the courtroom. Rogers was still on the stand, but a glance at Mr. Royce told me that he had elicited nothing new.
