He had one technical defect, if defect it might be called. In the larger affairs of his unhallowed business he displayed a mental adaptability, a talent to think quickly and shift his tactics to meet the suddenly arisen emergency, which was the envy of lesser underworld notables; but in smaller details of life he was prone to follow the line of least resistance, which is true of the most of us, honest and dishonest men the same. For instance, though he had half a dozen or more common aliases--names which he changed as he changed his collars--he pursued a certain fixed rule in choosing them, just as a man in picking out neckties might favor mixed weaves and varied patterns but stick always to the same general color scheme. He might be Vincent C. Marr, which was his proper name, or among intimates Chappy Marr. Then again he might be Col. Van Camp Morgan, of Louisiana; or Mr. Vance C. Michaels, a Western mine owner; or Victor C. Morehead; he might be a Markham or a Murrill or a Marsh or a Murphy as the occasion and the role and his humor suited. Always, though, the initials were the same. Partly this was for convenience--the name was so much easier to remember then--but partly it was due to that instinct for ordered routine which in a reputable sphere of endeavor would have made this man rather conventional and methodical in his personal habits, however audacious and resourceful he might have been on his public side and his professional. He especially was lucky in that he never acquired any of those mouth-filling nicknames such as Paper Collar Joe wore, and Grand Central Pete and Appetite Willie and the Mitt-and-a-Half Kid and the late Soapy Smith--picturesque enough, all of them, but giving to the wearers thereof an undesirable prominence in newspapers and to that added extent curtailing their usefulness in their own special areas of operation. Nor had he ever smelled the chloride-of-lime-and-circus-cage smell of the inside of a state's prison; no Bertillon sharp had on file his measurements and thumb prints, nor did any central office or detective bureau contain his rogues-gallery photograph. Times almost past counting he had been taken up on suspicion; more than once had been arrested on direct charges, and at least twice had been indicted. But because of connections with crooked lawyers and approachable politicians and venal police officials and because also of his own individual canniness, he always had escaped conviction and imprisonment. There was no stink of the stone hoosgow on his correctly tailored garments, and no barber other than one of his own choosing had ever shingled Chappy Marr's hair. Within reason, therefore, he was free to come and go, to bide and to tarry; and come and go at will he did until that unfortuitous hour when the affair of the wealthy Mrs. Propbridge and her husband came to pass.
