Systematic thieving and burglary for five years! Systematic, and always successful. What a masterful rogue must be the founder of this system! How secure he must be in his place, and his scheming, and what a foeman to encounter. It would be something to thwart, to baffle, and bring to justice a villain of such caliber.

After a while my thoughts turned back to Groveland. Certainly the mystery there was quite as deep, and the solution of it of more vital importance. But—Groveland was the mystery that I had touched and handled; Trafton was the mystery unseen.

So my mind returned to the latter subject, and when, hours later, we ran into the city, Groveland was still absent, and Trafton present, in my thoughts.


CHAPTER IV.
CHARTERING A DUMMY.

By the time I reached the city my arm, which needed fresh bandages, began to pain me, and I went straight to the office of a surgeon, well-known to fame, and to the detective service. He had bound up many a broken bone for our office, and we of the fraternity called him "Our Samaritan." Some of the boys, and, let me confess it, myself among the number, called him "Our old woman," as well, for, while he bandaged and healed and prescribed, he waged continued warfare upon our profession, or rather the dangers of it.

Of course, the country needed secret service men, and must have them, but there was an especial reason why each one of us should not be a detective. We were too young, or too old; we were too reckless, or we were cut out for some other career. In short, every patient that came under the hand of good Dr. Denham, became straightway an object of interest to his kindly old heart; and—strange weakness in a man of his cloth—he desired to keep us out of danger.

"So ho!" cried "our old woman," when I appeared before him with my bandaged arm, "here you are! I knew you'd be along soon. You've kept out of my clutches a good while. Arm, eh? Glad of it! I'll cut it off; I'll cut it off! That'll spoil one detective."
