In the tradition of the old Ace Doubles (flip one book over to read the second title), here is the twentieth Wildside Double: THE ASTEROID MURDER CASE: A Science Fiction Mystery, by Arthur Jean Cox. The murder of UN observer Carl Neal on a lonely outpost of the Asteroid Belt would seem to be only a small human tragedy, and yet it opens up vistas both of millennia of time and of unimaginable distances. Inspector Tom Dooley, Chief of Security of the American Sector of the Belt, together with his faithful "Watson," Ralph Phelps, must sift through the many clues to unravel the mystery of Neal's death--and then keep the aliens from interfering. A first-rate science fiction adventure combined with a classic mystery A COLLECTOR OF AMBROSES AND OTHER RARE ITEMS, by Arthur Jean Cox. Four tales of SF and fantasy, including the title story, in which three unscrupulous book collectors encounter a true "Completist"; "The Boy in the Iron Mask," which touches on the contamination of reality by dreams; "The Slaves of Moxon and Other Tales of Scientific Romance," in which the SF world has to deal with an alternate history version of...itself ; and "A Reply to L. Ron Hubbard." Great stories by a master storyteller.

Ross Rocklynne (1913-1988) was the pen name used by Ross Louis Rocklin, an American science fiction author active in the Golden Age of Science Fiction.

Born in 1913 in Ohio, Rocklynne was a regular contributor to the science fiction pulps. He was a professional guest at the first World Science Fiction Convention in 1939. Despite his numerous appearances and solid writing, Rocklynne never quite achieved the fame of his contemporaries Robert A. Heinlein, L. Sprague DeCamp, and Isaac Asimov. His most well known story is probably "The Men and the Mirror," first published in 1938.

Rocklynne partially retired from writing in the late 1950s, but made a notable return in the 1970s when his novelette "Ching Witch " was included in Harlan Ellison's original anthology, Again, Dangerous Visions (1972). "Ching Witch " was later nominated for a Nebula award.

This volume contains an annotated bibliography of Ross Rocklynne's work. It features an introduction by Arthur Jean Cox, plus an index.
