"The Malignant Entity" first featured in the magazine 'Weird Tales', written by Chicago born Otis Adelbert Kline. When police chief McGraw of the detective bureau arrives at Dr. Dorp's lab, he finds the scientist with his friend Evans. The detective asks the two men to help him examine the death scene of the eminent chemist and inventor, Albert Townsend. And when they get there, the whitened skeleton of Professor Townsend, fully clothed in garments that hung like rags on a scarecrow, lay on the floor of the laboratory. Dr. Dorp and his team set about trying to discover the mystery of Townsend's death…
A popular pulp era writer who served on the original Weird Tales editorial staff & appeared frequently in the magazine's early issues, Kline is perhaps best known for his novelistic feud with Edgar Rice Burroughs. He wrote "Planet of Peril" (1929) and two other novels set on the planet Venus and written in the storytelling form of the John Carter of Mars novels, prompting Burroughs to write his own stories set on Venus. In return, Kline wrote two novels set on Mars, as well as several jungle adventurers quite reminiscent of Burroughs's Tarzan.
In the mid-1930s Kline largely abandoned writing to concentrate on his career as a literary agent (most famously for fellow Weird Tales author Robert E. Howard, pioneer sword and sorcery writer and creator of Conan the Barbarian). Kline represented Howard from the Spring of 1933 until Howard's death in June 1936, and continued to act as literary agent for Howard's estate thereafter.
