"It's a great case," was the reply. "I'm mighty glad you happened to be on the scene at once."

He turned to the officer who had brought the card, and directed that Mrs. Jones should be admitted immediately.

A pretty young woman entered. She was of about the same height as the unfortunate victim of the tragedy in the restaurant, and much like her in build.

The faces did not resemble each other in outline, but the coloring was similar. There was a faint resemblance in the large, light blue eyes.

The hair was of the same peculiar shade, and nearly as luxuriant. But nobody would ever have mistaken one woman for the other, after a fair look at their faces.

The costumes, however, were positively identical. Mrs. John Jones, to all appearances, wore the very same clothes as Nick had seen upon the woman in room B.

Mrs. Jones was evidently very nervous, but she made a fine attempt to control herself.

"You have my husband under arrest, I believe," she said. "And he is accused, they say, of killing me."

She tried to smile, but it was rather a ghastly effort.

The superintendent motioned the woman to a seat.
