Andrzej had become particularly invested in […]

On 5 August 1941, at the end of his court martial, Josef Jakobs was handed the verdict of the court, likely in a sealed envelope. He took the envelope back to his cell at Wandsworth Prison. Did he open it immediately upon his return, or sit and stare at it. Given that he was still

Several years ago, I came across Harm Knol Bruins in the Guy Liddell diaries. His story intrigued me and I dug deeper. How had a Dutchman, caught with a wireless transmitter, managed to escape the hangman’s noose? More to the point, why had his wife—complicit in his crimes—been shot by firing squad, while he survived?

For the longest time (at least as early as 2012), the Imperial War Museum in London had a permanent display about wartime espionage. It featured a number of spy artifacts, as well as a few items from MI5’s secret wartime interrogation centre, Camp 020. One item in particular was quite intriguing, although hard to see

We know what the wireless sets carried by Germany’s LENA agents looked like. But what happens when someone actually tries to build one—and make it work? After years of research, photographs, measurements and experimentation, Thomas Hoeppe has done just that. Early in this blog’s history, in 2014, I wrote a post about the wireless transmitter/receivers

I’ve been to the Imperial War Museum many times over the years, mostly as a visitor drifting toward the “Secret War” gallery out of habit. This time was different. With a London research trip on the horizon, I wanted to get behind the glass and into the Research Room to examine a few unexhibited items

After a good stretch of writing, I’m stepping back for the spring and summer. The blog will be on hiatus for the next few months while I focus on work, travel, and a few ongoing projects. The research doesn’t stop—it just shifts out of public view for a while. If you’re new here, there’s a

I’ve known for decades that the First World War spies were buried at the East London Cemetery & Crematorium in Plaistow. It’s a long trek out to that corner of London, and I’d never found the time to get out there. During my visit to London in December 2025, however, I finally made the time.
