"Edinburgh is not a very big town," remarked Fullaway. "I reckon to run her down—if she's still there—within a couple of hours. It's our first duty, anyway. If she—as I guess she did—saw those jewels, then we know that James Allerdyke had them on him when he reached Hull, dead sure."
"And supposing she can tell that?" said Allerdyke. "What then? How does that help? The devils who got 'em have already had thirty-six hours' start of us!"

"Seems to me," he said presently, "seems very much to me that this has been a great thing!

As he and his companion walked along one of the platforms in the Waverley Station in Edinburgh that evening, on their way to a cab, Allerdyke suddenly uttered a sharp exclamation and seized the American by the elbow, twisting him round in front of a big poster which displayed the portrait of a very beautiful woman.
"Good Lord!" he exclaimed. "There she is! See? That's the woman. Man alive, we've hit it at once! Look!"
Fullaway turned and stared, not so much at the portrait as at the big lettering above and beneath it:
