The Queen of Zamba  The Queen of Zamba is a science fiction novel by American writer L. Sprague de Camp, the first book of his "Viagens Interplanetarias" series and its subseries of stories set on the fictional planet Krishna. It was written between November 1948 and January 1949 and first published in the magazine "Astounding Science Fiction" as a two-part serial in the issues for August and September 1949. It was first published in book form as a paperback by Ace Books in 1954 as an "Ace Double" issued back-to-back with Clifford D. Simak's novel "Ring Around the Sun". This version was editorially retitled Cosmic Manhunt and introduced a number of textual changes disapproved by the author. The novel was first issued by itself in another paperback edition under the title A Planet Called Krishna, published in England by Compact Books in 1966. A new paperback edition restoring the author's preferred title and text and including the Krishna short story "Perpetual Motion" was published by Dale Books in 1977. This edition was reprinted by Ace Books in 1982 as part of the standard edition of the Krishna novels. The novel has been translated into German, French, Italian, Czech, and Polish. An E-book edition was published by Gollancz's SF Gateway imprint on September 29, 2011 as part of a general release of de Camp's works in electronic form. As with all of the "Krishna" novels, the title of "The Queen of Zamba" has a "Z" in it, a practice de Camp claimed to have devised to keep track of them. Short stories in the series do not follow the practice, nor do "Viagens Interplanetarias" works not set on Krishna. Victor Hasselborg, a 22nd-century private eye, is hired by a Syrian businessman to track down his missing daughter Julnar Batruni, who it turns out has run off with adventurer Anthony Fallon. Immediate complications ensue when Hasselborg finds himself falling for Alexandra, Fallon's abandoned wife. Discovering that the fugitives have gone off-planet, he tracks them to the planet Krishna, an Earth-like world of the star Tau Ceti with humanoid inhabitants but a medieval culture. Disguising himself as a native Krishnan, Hasselborg goes after them, little-knowing he has entered a web of interplanetary intrigue, spying, and gun-running... Anthony Fallon, the antagonist in "The Queen of Zamba", would reappear in two later Krishna novels; as the protagonist of "The Tower of Zanid" and as a minor character in "The Swords of Zinjaban".
