The Expressman and the Detective

In 1858, money starts vanishing from the Adams Express Company's locked pouches on the Montgomery, Alabama run. Everyone knows who did it. Nobody can prove a thing. So the company hires a Chicago detective named Allan Pinkerton, who does something no one in America had done at this scale: he builds a months-long undercover operation around the suspect's entire life, placing operatives in his path, his social circle, and eventually his cell.

Pinkerton's 1874 account of the case launched an entire genre. It's part procedural, part con game run by the good guys, and part advertisement for the detective agency that would become a household name. The methods on display, surveillance, informants, psychological pressure, would define American detective work for a century, for better and for worse.

Our annotated edition works from the 1874 first edition and gives the case the scrutiny Pinkerton never invited: where his account holds up, where it's agency mythmaking, and what this new style of private policing meant for the country that embraced it.
