Barnes had not taken his eyes from the face of the little man during this recital. He was rapidly changing his opinion of Sprouse. There was sincerity in the voice and eyes of the secret agent.
"What led you to suspect that he is at Green Fancy, Mr. Sprouse?"
"History. It is known that this Mr. Curtis has spent a great deal of time in the country alluded to. As a matter of fact, his son, who lived in London, had rather extensive business interests there. This son was killed in the Balkan War several years ago. It is said that the man I am looking for was a friend of young Curtis, who married a Miss O'Dowd in London,--the Honourable Miss O'Dowd, daughter of an Irish peer, and sister of the chap you have met at Green Fancy. The elder Curtis was a close and intimate friend of more than one member of the royal family. Indeed, he is known to have been a welcome visitor in the home of a prominent nobleman, once high in the counsels of State. This man O'Dowd is also a friend of the man I am looking for. He went through the Balkan War with him. After that war, O'Dowd drifted to China, hoping no doubt to take a hand in the revolution. He is that sort. Some months ago he came to the United States. I forgot to mention that he has long considered this country his home, although born in Ireland. About six weeks ago a former equerry in the royal household arrived in New York. Through him I learned that the daughter of the gentleman in whose house the senior Mr. Curtis was a frequent guest had been in the United States since some time prior to the beginning of the war. She was visiting friends in the States and has been unable to return to her own land, for reasons that must be obvious. I may as well confess that her father was, by marriage, an uncle of the late ruler.
"Since the invasion and overthrow of her country by the Teutonic Allies, she has been endeavouring to raise money here for the purpose of equipping and supporting the remnants of the small army that fought so valiantly in defence of the crown. These men, a few thousand only, are at present interned in a neutral country. I leave you to guess what will happen if she succeeds in supplying them with arms and ammunition. Her work is being carried on with the greatest secrecy. Word of it came to the ears of her country's minister in Paris, however, and he at once jumped to a quick but very natural conclusion. She has been looked upon in court circles as the prospective bride of the adventurous cousin I am hunting for. The embassy has conceived the notion that she may know a great deal about the present whereabouts of the missing treasure. No one accuses her of duplicity, however. On the other hand, the man in the case is known to have pro-German sympathies. She may be loyal to the crown, but there is a decided doubt as to his loyalty. Of course, we have no means of knowing to what extent she has confided her plans to him. We do not even know that she is aware of his presence in this country. To bring the story to a close, I was instructed to keep close watch on the man O'Dowd. The ex-attache of the court to whom I referred a moment ago set out to find the young lady in question. I traced O'Dowd to this place. I was on the point of reporting to my superiors that he was in no way associated with the much-sought-after crown-cousin, and that Green Fancy was as free from taint as the village chapel, when out of a clear sky and almost under my very nose two men were mysteriously done away with at the very gates of the place. In fact, so positive was I that O'Dowd was all right, that I had started for Washington to send my report back home and wait for instructions. The killing of those two men changed the aspect completely. You will certainly agree with me after I have explained to you that the one known as Andrew Roon was no other than the equerry who had undertaken to find the--young woman."
