Allan Pinkerton invented the private detective agency, and he has gone down in history as a violent, sinister figure, a breaker of strikes, a spy for the Confederacy. When I saw this biography, I responded immediately. My thanks go to NetGalley and Tantor Media for the review copy. This book is available to the public now.

And here is where I must tell you to take my review with a grain of salt. I read less than a third of this nifty little nugget before it vanished forever; the fault was my own for failing to download it. I nearly never forget to do so, but this book caught me when I was distracted by other, nonliterary things, and I flaked. How disappointing! So I probably shouldn’t even review it, given that I don’t know what the middle or end looks like, but I was rather taken with it, and despite my background in U.S. history, I learned some things from it. If I had access to a copy right now, I’d finish it.

Instead, here’s what I will suggest: if you are considering reading this book because you enjoy biographies in general, and if you’ll have to pay full price to get it, do some more research first. There was the occasional dry passage in what I read, and I don’t know whether that part gets better or worse. However, if you have a specific interest in U.S. history during the American Civil War, or if you have a strong interest in American labor history, as I do, then I recommend this book to you without reservation. It comes in print, digital, and audio formats, but I only had access to the audio; the reader does a fine job. And when you get it, be sure to download it!
