I'm not sure if you are the same Cliff Stoll who wrote 'The Cuckoo's Egg', but if so I listened to the audio book in 2020 during the first part of the pandemic and I loved it. It was fascinating to see how a small billing discrepancy led you down such a rabbit hole. I also enjoyed the various solutions you came up with to crack the case using the technology of the time. I enjoy reading about the early days of the Internet. I have a sort of nostalgia for it, even though I didn't get on the net myself until around 1997. Your book hit a sweet spot for me with the combination of (now) retro technology and security. You might guess from this ham radio hacking post that I enjoy that kind of thing. If you are that Cliff Stoll, thanks for sharing your story!

I would like to echo your sentiment, that book was so good and has made me curious about the physical and digital world in so many different ways.

Our hero didn’t do that, that was marketing! :)
