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!
