The Dual World
There is a lost continent among the humid swamps and tractless wastes of Venus, a world unexplored, unknown, and home to all manner of strange and unusual creatures. Not one to be shown-up by his new partner and captain, Gerry Carlyle, the intrepid Tommy Strike ventures out on his own to capture a monster no other hunter has ever laid eyes on.
The Dual World first appeared the June, 1938 issue of Thrilling Wonder Stories.
