Hamilton started, and drew back.

The pair were standing together in earnest conversation, the man facing him, the girl with her back turned.

"What does this mean?" gasped Hamilton aloud. "What can this secret meeting mean? Why—yes, I'm certainly not mistaken—it's Krail—Felix Krail, by all that's amazing!"

CHAPTER XXXI

DESCRIBES A CURIOUS CIRCUMSTANCE

To Hamilton it was evident that the man Krail, now smartly dressed in country tweeds, was telling the girl something which surprised her. He was speaking quickly, making involuntary gestures which betrayed his foreign birth, while she stood pale, surprised, and yet defiant. The Baron's secretary was not near enough to overhear their words. Indeed, he remained there in concealment in order to watch.

Why had Gabrielle met Felix Krail—of all men? She was beautiful. Yes, there could be no two opinions upon that point, Edgar decided. And yet how strange it all was, how very remarkable, how romantic!

The man was evidently endeavouring to impress upon the girl some plain truths to which, at first, she refused to listen. She shrugged her shoulders impatiently and swung her walking-stick before her in an attempt to remain unconcerned. But from where Hamilton was standing he could plainly detect her agitation. Whatever Krail had told her had caused her much nervous anxiety. What could it be?

Across the meadows, beyond the river, could be seen the lantern-tower of old Fotheringhay church, with the mound behind where once stood the castle where ill-fated Mary met her doom.

And as the Baron's secretary watched, he saw that the foreigner's attitude was gradually changing from persuasive to threatening. He was speaking quickly, probably in French, making wild gestures with his hands, while she had drawn back with an expression of alarm. She was now, it seemed, frightened at the man, and to Edgar Hamilton this increased the interest tenfold.
