In William Johnstone's Behind the Iron (Penguin Random House 2018), Harry 'Hank' Fallon, former deputy US Marshall and paroled prisoner, has a difficult background that is complicated by a rich mix of law and disorder. He was released from prison early for saving the lives of several guards and ended up working for the American Detective Agency, a wannabe Pinkerton Detective Agency who would never live up to that sort of stellar reputation. He knows they're using him but it doesn't bother him much, because he's using them, too.
Harry Fallon had been at the Illinois State Penitentiary in Joliet, saving the lives of a few guards during a bloody riot, and that act of bravery, kindness, humanity—just a spur-of-the-moment decision, truthfully—had led to a parole for Harry Fallon, former deputy United States marshal for Judge Isaac Parker’s court in Fort Smith, Arkansas. Fallon had been given a job at Werner’s Wheelwright in Chicago and a place to live at Missus Ketchum’s Boarding House near Lake Michigan. And then this small man had changed Fallon’s life.
While he was in prison, his family was killed. Now, he will take any job that allows him to find the killers and bring justice to them, even if it's of the Wild West variety. Luckily, he is well-suited for fighting bad guys. He is a fast thinker, quick with his guns, and about as powerful as anyone he might run into. Like most westerns, things don’t go quite as planned, but as a reader, that only makes it more exciting.
The story is set in the late 1800's with a well-developed plot peopled by vibrant and busy characters. While it’s not the typical Wild West with small towns, horses, range wars, and untamed people who went West for freedom, it's definitely a look into a long-gone era where the rule of law meant something only if enforced with a gun.
This is the second in the Hank Fallon Westerns series. I couldn't be happier. BTW, the tagline is right. It is quite violent.
