"Evidently that was what she had burned. She'd taken care to crumple the ashes so that it was an impossibility to get a shred of direct evidence, not that it would have made any difference if she hadn't. The government never prosecutes matters of this kind, except in time of war. They merely warn the culprit to leave the country and never return--which is the reason that, while you'll find a number of very interesting foreigners in Washington at the present moment, the Countess Sylvia Stefani is not among them. Neither is the personage to whom her letter was addressed. He was 'recalled' a few weeks later." XXI A MILLION-DOLLAR QUARTER "What's in the phial?" I inquired one evening, as Bill Quinn, formerly of the United States Secret Service, picked up a small brown bottle from the table in his den and slipped it into his pocket. "Saccharine," retorted Quinn, laconically. "Had to come to it in order to offset the sugar shortage. No telling how long it will continue, and, meanwhile, we're conserving what we have on hand. So I carry my 'lump sugar' in my vest pocket, and I'll keep on doing it until conditions improve. They say the trouble lies at the importing end. Can't secure enough sugar at the place where the ships are or enough ships at the place where the sugar is. "This isn't the first time that sugar has caused trouble, either. See that twenty-five-cent piece up there on the wall? Apparently it's an ordinary everyday quarter. But it cost the government well over a million dollars, money which should have been paid in as import duty on tons upon tons of sugar. "Yes, back of that quarter lies a case which is absolutely unique in the annals of governmental detective work--the biggest and most far-reaching smuggling plot ever discovered and the one which took the longest time to solve. "Nine years seems like a mighty long time to work on a single assignment, but when you consider that the Treasury collected more than two million dollars as a direct result of one man's labor during that time, you'll see that it was worth while." * * * * * The whole thing really started when Dick Carr went to work as a sugar sampler [continued Quinn, his eyes fixed meditatively upon the quarter on the wall]. Some one had tipped the department off to the fact that phony sampling of some sort was being indulged in and Dick managed to get a place as assistant on one of the docks where the big sugar ships unloaded. As you probably know, there's a big difference in the duty on the different grades of raw sugar; a difference based upon the tests made by expert chemists as soon as the cargo is landed. Sugar which is only ninety-two per cent pure, for example, comes in half-a-cent a pound cheaper than that which is ninety-six per cent pure, and the sampling is accomplished by inserting a thin glass tube through the wide meshes of the bag or basket which contains the sugar.
