I have a confession to make: I’m having way too much fun writing this third book in the Concordia Wells Mystery series! I’m hoping you’ll enjoy reading it, too. (It should be out by late summer).

One component of the story, set in 1898 Hartford, Connecticut, involves the use of dynamite by the bad guys. I won’t go into any more of the plot than that – you’ll want to read it for yourselves when the book comes out.

So I needed to get educated about the use of bombs in the late 1890s. Time for some research! My job is sooo cool.

I learned about famous anarchists in America and Europe, such as Emma Goldman and Alexander Berkman; incidents such as the Haymarket Riot (Chicago, 1886), where someone threw dynamite at police as they were trying to break up a striking workers’ demonstration, and the bombing of the Royal Observatory in Greenwich (1894); assassination attempts with the use of explosives, such as that of Alexander II of Russia (1881).

That’s just a sampling. Those anarchists were a busy crew.

I also wondered what these devices looked like. How would they work? What were their limitations? How would one make them from scratch?

I found this book, written in 1884 by Johann Most, a German-born activist who emigrated to the U.S. and gained much of his knowledge of explosives by working in an explosives plant in New Jersey. It’s really a pamphlet, being only 74 pages (originally written in German), as a guide for his like-minded friends back in central Europe.

In case you can’t read it, here’s the subtitle:

A Handbook of Instruction Regarding the Use and Manufacture of Nitroglycerine, Dynamite, Gun-cotton, Fulminating Mercury, Bombs, Arsons, Poisons, Etc

I mean, really – who can pass up a title like that? So I ordered it from Amazon, to the despair of my security-clearance hubby…gee, honey, I don’t see the problem…




But if you didn’t want to make the explosives yourself, where could you lay your hands on them in the late-nineteenth century?

Here’s one of the biggest suppliers in the U.S. at the time:

The California Powder Works ad above depicts Hercules (the brand name of that particular explosives line, which later became the new company name) slaying the “giants.” In this case, the “giants” aren’t mythological: it’s a jab at its biggest competitor, Giant Powder Works. Their products (gunpowder, blasting caps, dynamite, etc) were marketed to railroad companies, mining companies, farmers, and sportsmen.

I’m seeing some possibilities here.

My best source of all: 

The most indispensable resource for me was a person – Jay Holmes, part of the spy thriller writing team of Bayard and Holmes. Piper Bayard graciously put me in contact with him, since his day job is, shall we say, of the covert variety. There’s no way I’d be able to find him on my own…and survive the experience.  In back-and-forth emails, he patiently answered all of my questions. Thank you, Jay! And don’t worry: I’ll make clear in the book acknowledgments that any errors are mine, not yours. 😉 

So, what adventures have your internet searches taken you on lately? I’d love to hear from you.

Until next time,
