The Byworlder

For three years a visitor from Sigma Draconis has circled the Earth, waiting, and the one who works out why is Skip Wayburn: artist, drifter, sigaroon. Signet's copy heads the whole thing The Secret of the Sigman, which is not the title on the front. Anderson ran it in Fantastic in June and August 1971, and Signet had it out as a paperback that September.
