Book excerpt: These early works by various authors were originally published in the late 19th century and early 20th century and we are now republishing them with a brand new introduction as part of our Cryptofiction Classics series. 'Weird Tales of Weird Tails' contains a collection of short stories about supernatural felines, and includes 'The King of the Cats' by Thomas Lyttelton (1807), 'The Gray Cat' by Barry Pain (1901), 'Ancient Sorceries' by Algernon Blackwood (1908), and many more. Therianthropy – the metamorphosis of humans into animals – is one of literature's oldest themes, and the werecat appears in some form in the folklore of virtually every global culture. African legends are replete with tales of people morphing into lions or leopards; Asian folklore features the often malevolent figure of the weretiger; and in Europe, werecats are found in the writings of Ancient Greece, and were explicitly condemned as heretical creatures during the witch trials of the early Modern period. The Cryptofiction Classics series contains a collection of wonderful stories from some of the greatest authors in the genre, including Ambrose Bierce, Arthur Conan Doyle, Robert Louis Stevenson, and Jack London. From its roots in cryptozoology, this genre features bizarre, fantastical, and often terrifying tales of mythical and legendary creatures. Whether it be giant spiders, werewolves, lake monsters, or dinosaurs, the Cryptofiction Classics series offers a fantastic introduction to the world of weird creatures in fiction.
