With a formal inclination of his head, and a word or two corroborative of the officer's estimate of the weather, Doctor James continued his somewhat rapid progress. Three times that night had a patrolman accepted his professional card and the sight of his paragon of a medicine case as vouchers for his honesty of person and purpose. Had any one of those officers seen fit, on the morrow, to test the evidence of that card he would have found it borne out by the doctor's name on a handsome doorplate, his presence, calm and well dressed, in his well-equipped office--provided it were not too early, Doctor James being a late riser--and the testimony of the neighborhood to his good citizenship, his devotion to his family, and his success as a practitioner the two years he had lived among them. Therefore, it would have much surprised any one of those zealous guardians of the peace could they have taken a peep into that immaculate medicine case. Upon opening it, the first article to be seen would have been an elegant set of the latest conceived tools used by the "box man," as the ingenious safe burglar now denominates himself. Specially designed and constructed were the implements--the short but powerful "jimmy," the collection of curiously fashioned keys, the blued drills and punches of the finest temper--capable of eating their way into chilled steel as a mouse eats into a cheese, and the clamps that fasten like a leech to the polished door of a safe and pull out the combination knob as a dentist extracts a tooth. In a little pouch in the inner side of the "medicine" case was a four-ounce vial of nitroglycerine, now half empty. Underneath the tools was a mass of crumpled banknotes and a few handfuls of gold coin, the money, altogether, amounting to eight hundred and thirty dollars. To a very limited circle of friends Doctor James was known as "The Swell 'Greek.'" Half of the mysterious term was a tribute to his cool and gentlemanlike manners; the other half denoted, in the argot of the brotherhood, the leader, the planner, the one who, by the power and prestige of his address and position, secured the information upon which they based their plans and desperate enterprises. Of this elect circle the other members were Skitsie Morgan and Gum Decker, expert "box men," and Leopold Pretzfelder, a jeweller downtown, who manipulated the "sparklers" and other ornaments collected by the working trio. All good and loyal men, as loose-tongued as Memnon and as fickle as the North Star.
