Excerpt:
"The following pages narrate a story of detective experience, which, in many respects, is alike peculiar and interesting, and one which evinces in a marked degree the correctness of one of the cardinal principles of my detective system, viz.: "That crime can and must be detected by the pure and honest heart obtaining a controlling power over that of the criminal." The history of the old man who, although in the possession of unlimited wealth, leaves the shores of his native land to escape the imagined dangers of assassination, and arrives in America, only to meet his death—violent and mysterious."

Allan Pinkerton (1819-1884) was a Scottish American detective and spy, best known for creating the Pinkerton National Detective Agency. Pinkerton started with detective work back in Scotland, and in 1849 he was appointed as the first police detective in Chicago. Year later he partnered with Chicago attorney Edward Rucker in forming the Detective Agency which became famous for solving a series of train robberies during the 1850s. Pinkerton produced numerous popular detective books, based on his own exploits and those of his agents.
