After returning from Iraq, Johnson began fly-fishing, which led him to the story that would become his true crime book,
The Feather Thief. The story is about how an American flutist,
Edwin Rist stole remains of rare birds from the
Natural History Museum in England. Hobbyists pay high prices for the feathers of exotic birds, including fly-fishers, who use them to catch fish. He learned of the heist when a guide from New Mexico told the story, leading to a five-year period of research and interviews, including with Rist.
The Feather Thief was named an Amazon Best Book of 2018, shortlisted for a Crime Writers Association Gold Dagger Award, a finalist for the 2019 Edgar Awards (Best Fact Crime), a semifinalist for the Goodreads Choice Awards, and longlisted for the Andrew Carnegie Medal.
