Pseudonym of Katherine Mary Deville Dalton Renoir (1881-1963) Katherine Dalton was born in Hammersmith, London in 1881, the only child of a Canadian father and English mother. The author wrote two well-received early novels, Olive in Italy (1909), and The Sword of Love (1920). However, her career in crime fiction did not begin until 1924, after which Moray Dalton published twenty-nine mysteries, the last in 1951. The majority of these feature her recurring sleuths, Scotland Yard inspector Hugh Collier and private inquiry agent Hermann Glide. Moray Dalton married Louis Jean Renoir in 1921, and the couple had a son a year later. The author lived on the south coast of England for the majority of her life following the marriage. She died in Worthing, West Sussex, in 1963.

Violet Mary Firth Evans (better known as Dion Fortune), was a British occultist and author. Her pseudonym was inspired by her family motto "Deo, non fortuna" (Latin for "by God, not fate"). From 1919 she began writing a number of novels and short stories that explored various aspects of magic and mysticism, including The Demon Lover, The Winged Bull, The Goat-Foot God, and The Secrets of Dr. Taverner. This latter is a collection of short stories based on her experiences with Theodore Moriarty. Two of her novels, The Sea Priestess and Moon Magic, became influential within the religion of Wicca, especially upon Doreen Valiente. Of her non-fiction works on magical subjects, the best remembered of her books are; The Cosmic Doctrine, meant to be a summation of her basic teachings on mysticism; The Mystical Qabalah, an introduction to Hermetic Qabalah; and Psychic Self Defence, a manual on how to protect oneself from psychic attacks. Though some of her writings may seem dated to contemporary readers, they have the virtue of lucidity and avoid the deliberate obscurity that characterised many of her forerunners and contemporaries.

Blackwood was born in Shooter's Hill (today part of south-east London, but then part of northwest Kent) and educated at Wellington College. His father was a Post Office administrator who, according to Peter Penzoldt, "though not devoid of genuine good-heartedness, had appallingly narrow religious ideas." Blackwood had a varied career, farming in Canada, operating a hotel, as a newspaper reporter in New York City, and, throughout his adult life, an occasional essayist for various periodicals. In his late thirties, he moved back to England and started to write stories of the supernatural. He was very successful, writing at least ten original collections of short stories and eventually appearing on both radio and television to tell them. He also wrote fourteen novels, several children's books, and a number of plays, most of which were produced but not published. He was an avid lover of nature and the outdoors, and many of his stories reflect this. Lovecraft wrote of Blackwood: "He is the one absolute and unquestioned master of weird atmosphere." His powerful story "The Willows," which effectively describes another dimension impinging upon our own, was reckoned by Lovecraft to be not only "foremost of all" Blackwood's tales but the best "weird tale" of all time. Among his thirty-odd books, Blackwood wrote a series of stories and short novels published as John Silence, Physician Extraordinary (1908), which featured a "psychic detective" who combined the skills of a Sherlock Holmes and a psychic medium. Blackwood also wrote light fantasy and juvenile books. The son of a preacher, Blackwood had a life-long interest in the supernatural, the occult, and spiritualism, and firmly believed that humans possess latent psychic powers. The autobiography Episodes Before Thirty (1923) tells of his lean years as a journalist in New York. In the late 1940s, Blackwood had a television program on the BBC on which he read . . . ghost stories!

Major Hesketh Vernon Prichard, later Hesketh-Prichard, DSO, MC, FRGS, FZS (17 November 1876 – 14 June 1922) was an explorer, adventurer, big-game hunter and marksman who made a significant contribution to sniping practice within the British Army during the First World War. Concerned not only with improving the quality of marksmanship, the measures he introduced to counter the threat of German snipers were credited by a contemporary with saving the lives of over 3,500 Allied soldiers. During his lifetime, he also explored territory never seen before, played cricket at first-class level, including on overseas tours, wrote short stories and novels (one of which was turned into a Douglas Fairbanks film) and was a successful newspaper correspondent and travel writer. His many activities brought him into the highest social and professional circles. Despite a lifetime's passion for shooting, he was an active campaigner for animal welfare and succeeded in seeing legal measures introduced for their protection.
