Murray Leinster (June 16, 1896 – June 8, 1975) was a nom de plume of William Fitzgerald Jenkins, an award-winning American writer of science fiction and alternate history. He wrote and published more than 1,500 short stories and articles, 14 movie scripts, and hundreds of radio scripts and television plays. Leinster was born in Norfolk, Virginia, the son of George B. Jenkins and Mary L. Jenkins. His father was an accountant. Although both parents were born in Virginia, the family lived in Manhattan in 1910, according to the 1910 Federal Census. He began his career as a freelance writer before World War I; he was two months short of his 20th birthday when his first story, "The Foreigner", appeared in the May 1916 issue of H. L. Mencken's literary magazine The Smart Set. Over the next three years, Leinster published ten more stories in the magazine. During and after World War I, he began appearing in pulp magazines like Argosy, Snappy Stories, and Breezy Stories. He continued to appear regularly in Argosy into the 1950s. When the pulp magazines began to diversify into particular genres in the 1920s, Leinster followed suit, selling jungle stories to Danger Trails, westerns to West and Cowboy Stories, detective stories to Black Mask and Mystery Stories, horror stories to Weird Tales, and even romance stories to Love Story Magazine under the pen name Louisa Carter Lee. Leinster's first science fiction story, "The Runaway Skyscraper", appeared in the February 22, 1919 issue of Argosy, and was reprinted in the June 1926 issue of Hugo Gernsback's first science fiction magazine, Amazing Stories. In the 1930s, he published several science fiction stories and serials in Amazing and Astounding Stories (the first issue of Astounding included his story "Tanks"). He continued to appear frequently in other genre pulps such as Detective Fiction Weekly and Smashing Western, as well as Collier's Weekly beginning in 1936 and Esquire starting in 1939. Leinster is credited with the invention of parallel universe stories. Four years before Jack Williamson's The Legion of Time came out, Leinster published his "Sidewise in Time" in the June 1934 issue of Astounding. Leinster's vision of extraordinary oscillations in time ('sidewise in time') had a long-term impact on other authors, for example Isaac Asimov's "Living Space", "The Red Queen's Race", and The End of Eternity.

Orejas de ellos, the things who listen, whispered the superstitious fishermen when the strange occurrences began off the Philippine coast. How else explain the sudden disappearance of a vessel beneath a mysterious curtain of foam? The writhings of thousands of maddened fish trapped in a coffinlike area of ocean? What monsters gorged at the bottom of the Luzon Deep and what were their plans? Radar expert Terry Holt and the crew of the Esperance had to devise a weapon against the horrifying creatures which threatened mankind with extinction. Here are terror, excitement, and the clutch of cold death as combined by a master hand in the field of science fiction.

Cassandra Leung’s been a sea monster trainer ever since she could walk, raising genetically engineered beast to defend ships crossing the NeoPacific ... until pirates snatch her from the blood-stained decks.

In this gripping action-adventure novel, Murray Leinster turns away from the interplanetary settings that typically form the backdrop of his fiction and instead delves into one of the most mysterious places on Earth: the darkest depths of the sea. Expert radar operator Terry Holt is summoned to an unusual top-secret assignment off the coast of the Philippines. What could be responsible for the strange clues that have been surfacing there?

Beasts of the Deep: Sea Creatures and Popular Culture offers its readers an in-depth and interdisciplinary engagement with the sea and its monstrous inhabitants; through critical readings of folklore, weird fiction, film, music, radio and digital games. Within the text there are a multitude of convergent critical perspectives used to engage and explore fictional and real monsters of the sea in media and folklore. The collection features chapters from a variety of academic perspectives; post- modernism, psychoanalysis, industrial-organisational analysis, fandom studies, sociology and philosophy are featured. Under examination are a wide range of narratives and media forms that represent, reimagine and create the Kraken, mermaids, giant sharks, sea draugrs and even the weird creatures of H.P. Lovecraft. Beasts of the Deep offers an expansive study of our sea-born fears and anxieties, that are crystallised in a variety of monstrous forms. Repeatedly the chapters in the collection encounter the contemporary relevance of our fears of the sea and its inhabitants – through the dehumanising media depictions of refugees in the Mediterranean to the encroaching ecological disasters of global warming, pollution and the threat of mass marine extinction.
