Charismatic, handsome, and fiercely loyal, Isaac Bell is a no-nonsense private detective at the Van Dorn Detective Agency. Travelling all over early 20th century America in pursuit of justice for his clients, chasing down a steam train in a sports automobile is all in a day's work for Bell. And while he's on the trail of thieves, killers, and sometimes much worse, he'll have to use his every last wit to stay ahead of those he seeks, and to stay alive.
