Nona walked on quickly and with a speed and careless grace that covered the ground without apparent effort.

She was looking extremely well, but above all other things Nona Davis appeared supremely interested. For some reason, still unknown to her, she had been more stirred and excited by the coming into Russia than any country she had yet seen. She both admired and feared the Russian people, with their curious combination of poetry and stupidity, of dullness and passion. Before returning to her own land she meant to try and understand them better. For somewhere she had read that the future art of the world was to come forth from Russia. It is the Slavic temperament and not the Anglo-Saxon that best expresses itself in music and literature.

Nona’s errand this afternoon was a curious and puzzling one, fraught with unnecessary mystery.

Four days before, a Russian boy about twelve years old had appeared at the gate of the fortress at Grovno, bearing a note addressed to Miss Nona Davis. Oddly enough, although the note was written in perfect English, it was not signed. In spite of this it requested that the American girl come to a small house about a mile and a half away to see a former friend.

But who the friend could be, not one of the three girls could imagine. Yet they scarcely talked of anything else. Nona had no acquaintances in Russia save the people she had met in connection with her work, and there was no one in her past whom she could possibly conceive of having come into Russia as a tourist at such a time.

Therefore it was Mildred Thornton’s and Barbara Meade’s opinion that Nona should pay not the slightest heed to such a communication. Anonymous letters lead to nothing but evil. But in spite of their objections, here at the first possible opportunity Nona was obeying the behest. Probably she could not have explained why, for she was too sensible not to appreciate that possible discomfort and even danger might lie ahead of her. Perhaps as much as anything she was actuated by a spirit of sheer adventure.

So it is little wonder that during her walk Nona’s thoughts were now and then engaged with her own affairs. Yet after a little her attention wandered from the immediate future and she fell to recalling the history of the past years’ experiences, her own and her three friends.

No wonder Barbara was often lonely and homesick for Dick Thornton.

She had become engaged to him on the fog-bound trip she had made with him in getting Eugenia safely out of Belgium. Remembering Eugenia’s escape, Nona said a short prayer of thankfulness. After her hiding of the Belgian officer and his family from the German authorities, she would never have been allowed to leave Belgium unpunished had she not been an American woman. Remembering the fate of the English girl who had committed the same crime, Nona appreciated how much they had to be thankful for.

And now Eugenia was married to Captain Castaigne, the young French officer. Curious that among the four of them who had come from the United States to do Red Cross work among the Allies, Eugenia should be the first to marry! She, a New England old maid, disapproving of matrimony and, above all, of international marriages!
