Summary
What happens when the guy measuring your lawn for code violations is also one of the most prolific serial killers in American history? Dennis Rader spent 31 years hiding in plain sight as a church leader, security alarm installer, and suburban dad while methodically stalking and murdering at least 10 people in Wichita, Kansas. He called himself BTK. He wrote letters to newspapers. He answered to "yes sir" in court while describing strangulation techniques. And in 2005, he asked police one fatal question about a floppy disk that would finally end his reign of terror. This is the story of how narcissism, metadata, and a purple floppy disk brought down one of the most calculated killers America has ever seen.
