The title is an editorial invention for the collected Miro Hetzel stories: ”Freitzke's Turn” (1977) and ”The Dogtown Tourist Agency” (1975).
Meet Miro Hetzel, Galactic Effectuator. He's part gentleman, part detective, part fraud and his trail of exploits cuts through some of the most improbable civilisations in the univers. Join him in a triop to the planet Maz, whose natives are so fierce that they'll fight three battles before lunch and then dine on the enemy – a planet that only a man with Miro Hetzel's steely nerve would dare to visit at all.
John Holbrook "Jack" Vance (1916–2013) was an American mystery, fantasy and science fiction writer. Though most of his work has been published as by Jack Vance, he also wrote 11 mystery novels using his full name John Holbrook Vance, three under the pseudonym Ellery Queen, and once each using the pseudonyms Alan Wade, Peter Held, John van See, and Jay Kavanse.
Vance won the World Fantasy Award for Life Achievement in 1984 and he was a Guest of Honor at the 1992 World Science Fiction Convention in Orlando, Florida. The Science Fiction and Fantasy Writers of America made him its 14th Grand Master in 1997 and the Science Fiction Hall of Fame inducted him in 2001, its sixth class of two deceased and two living writers.
