The United States authorities did not know why Quintana had come to America. They realised merely that he arrived for no good purpose; and they had meant to arrest and hold him for extradition if requested; for deportation as an undesirable alien anyway. Only two men in America knew that Quintana had come to the United States for the purpose of recovering the famous "Flaming Jewel," stolen by him from the Grand Duchess Theodorica of Esthonia; and stolen from Quintana, in turn, by a private soldier in an American Forestry Regiment, on leave in Paris. This soldier's name, probably, was Michael Clinch. One of the men who knew why Quintana might come to America was James Darragh, recently of the Military Intelligence, but now passing as a hold-up man under the name of Hal Smith, and actually in the employment of Clinch at his disreputable "hotel" at Star Pond in the North Woods. The other man who knew why Quintana had come to America was Emanuel Sard, a Levantine diamond broker of New York, Quintana's agent in America. * * * * * Now, as the October days passed without any report of Quintana's detention, Darragh, known as Hal Smith at Clinch's dump, began to suspect that Quintana had already slid into America through the meshes of the police. If so, this desperate international criminal could be expected at Clinch's under some guise or other, piloted thither by Emanuel Sard. So Hal Smith, whose duty was to wash dishes, do chores, and also to supply Clinch's with "mountain beef" -- or deer taken illegally -- made it convenient to prowl every day in the vicinity of the Ghost Lake road. He was perfectly familiar with Emanuel Sard's squat features and parrot nose, having robbed Mr. Sard of Quintana's cipher and of $4,000 at pistol point. And one morning, while roving around the guide's quarters at Ghost Lake Inn, Smith beheld Sard himself on the hotel veranda, in company with five strangers of foreign aspect. During the midday dinner Smith, on pretense of enquiring for a guide's license, got a look at the Inn ledger. Sard's signature was on it, followed by the names of Henri Picquet, Nicolas Salzar, Victor Georgiades, Harry Beck, and Jose Sanchez. And Smith went back through the wilderness to Star Pond, convinced that one of these gentlemen was Quintana, and the remainder, Quintana's gang; and that they were here to do murder if necessary in their remorseless quest of "The Flaming Jewel." Two million dollars once had been offered for the Flaming Jewel; and had been refused. Clinch probably possessed it. Smith was now convinced of that. But he was there to rob Clinch of it himself. For he had promised the little Grand Duchess to help recover her Erosite jewel; and now that he had finally traced its probably possession to Clinch, he was wondering how this recovery was to be accomplished.
