A hidden route, a careful question, a small mistake: quiet details can expose a secret scheme.
In On Secret Service, William Nelson Taft gathers true detective stories about government agents, spies and smugglers. These short accounts follow investigations through patient watching, disguise and careful questioning. The action lies in pursuit and discovery: agents track people who try to move goods, money or secrets past the authorities, while looking for the detail that does not fit.
Rather than follow one hero through a single plot, this collection opens a series of cases. Its central concerns are work that happens out of sight, the patient details that solve cases, smugglers who test the law, and the courage and judgment agents need. Each investigation brings a practical question: when should an agent keep watching, and when is it time to act?
What you’ll discover
- Work out of sight Look beyond public view at the quiet tasks government agents carry out.
- The detail that matters Follow how careful watching and questioning turn small inconsistencies into trails of evidence.
- Smugglers against the law Explore the hiding places and routes that make pursuit a test of patience.
- Courage balanced with judgment Consider the choices agents face when help is distant and action carries risk.
- Real cases, readable stories Discover factual accounts that bring the appeal of detective stories to government investigations.

A retired agent tells the tales from his den
The book is built as a string of quiet evenings. Bill Quinn, once of the United States Secret Service, sits in his den or on his porch while a friend listens. A bad leg, won in a raid on counterfeiters, keeps him in a comfortable Treasury job. He can no longer chase crooks, so he chases them in memory.
Quinn has firm views about his trade. A mail course that promises to make detectives in ten lessons fills him with scorn. He says a detective needs only three things. They are common sense, sharp powers of observation and perseverance.
