Mystery fiction is a loosely-defined term.

It is often used by Dime Mystery, which started out as an ordinary crime fiction magazine but switched to "weird menace" during the latter part of 1933.

An early work of modern mystery fiction, Das Fräulein von Scuderi by E.T.A. Hoffmann (1819), was an influence on The Murders in the Rue Morgue by Edgar Allan Poe (1841). Wilkie Collins' epistolary novel The Woman in White was published in 1860, while The Moonstone (1868), is often thought to be his masterpiece. In 1887 Arthur Conan Doyle introduced Sherlock Holmes, whose mysteries are said to have been singularly responsible for the huge popularity in this genre. The genre began to expand near the turn of century with the development of dime novels and pulp magazines. Books were especially helpful to the genre with many authors writing in the genre in the 1920s. An important contribution to mystery fiction in the 1920s was the development of the juvenile mystery by Edward Stratemeyer. Stratemeyer originally developed and wrote the Hardy Boys and Nancy Drew mysteries written under the Franklin W. Dixon and Carolyn Keene pseudonyms respectively (and were later written by his daughter, Harriet Adams, and other authors). The 1920s also gave rise to one of the most popular mystery authors of all time, Agatha Christie, whose works include Murder on the Orient Express (1934), Death on the Nile (1937), and the world's best-selling mystery And Then There Were None (1939).

A bobblehead doll, also known as a bobbing head doll, nodder, or wobbler, is a type of collectible toy. Its head is often oversized compared to its body. Instead of a solid connection, its head is connected to the body by a spring or hook in such a way that a light tap will cause the head to bobble, hence the name.

Although bobblehead dolls have been made with a wide variety of figures such as breakfast cereal mascot Count Chocula, beat generation author Jack Kerouac, and Nobel-prize-winning geneticist James D. Watson, the figure is most associated with athletes, especially baseball players. Bobblehead dolls are sometimes given out to ticket buyers at sporting events as a promotion. Corporations including Taco Bell (the 'Yo Quiero Taco Bell' Chihuahua), McDonald's (Ronald McDonald), and Empire Today (The Empire Man) have also produced popular bobbleheads of the characters used in their advertisements.

The earliest known reference to a bobblehead is thought to be in Nikolai Gogol's 1842 short story The Overcoat, in which the main character's neck was described as "like the necks of plaster cats which wag their heads". The modern bobblehead first appeared in the 1950s. By 1960, Major League Baseball had gotten in on the action and produced a series of papier-mache bobblehead dolls, one for each team, all with the same cherubic face. The World Series held that year brought the first player-specific baseball bobbleheads, for Roberto Clemente, Mickey Mantle, Roger Maris, and Willie Mays, still all with the same face. Over the next decade, after a switch in materials from papier-mache to ceramic, bobbleheads would be produced for other sports, as well as cartoon characters. One of the most famous bobbleheads of all time also hails from this era: The Beatles bobblehead set, which is a valuable collectible today. By the mid-1970s, though, the bobblehead craze was in the process of winding down.

Israel Zangwill (January 21, 1864 – August 1, 1926) was a British humorist and writer.

Zangwill was born in London on January 21, 1864 in a family of Jewish immigrants from Czarist Russia, to Moses Zangwill from what is now Latvia and Ellen Hannah Marks Zangwill from what is now Poland. He dedicated his life to championing the cause of the oppressed. Jewish emancipation, women's suffrage, assimilationism, territorialism and Zionism (a Jewish liberation movement) were all fertile fields for his pen. His brother was also a writer, the novelist Louis Zangwill, and his son was the prominent British psychologist, Oliver Zangwill.

Zangwill received his early schooling in Plymouth and Bristol. When he was nine years old Zangwill was enrolled in the Jews' Free School in Spitalfields in east London, a school for Jewish immigrant children. The school offered a strict course of both secular and religious studies while supplying clothing, food, and health care for the scholars; today one of its four houses is named Zangwill in his honour. At this school young Israel excelled and even taught part-time, moving up to become a full-fledged teacher. While teaching, he studied for his degree in 1884 from the University of London, earning a BA with triple honours.

Edgar Allan Poe (born Edgar Poe; January 19, 1809 – October 7, 1849) was an American author, poet, editor and literary critic, considered part of the American Romantic Movement. Best known for his tales of mystery and the macabre, Poe was one of the earliest American practitioners of the short story and is considered the inventor of the detective fiction genre. He is further credited with contributing to the emerging genre of science fiction. He was the first well-known American writer to try to earn a living through writing alone, resulting in a financially difficult life and career.

He was born as Edgar Poe in Boston, Massachusetts; he was orphaned young when his mother died shortly after his father abandoned the family. Poe was taken in by John and Frances Allan, of Richmond, Virginia, but they never formally adopted him. He attended the University of Virginia for one semester but left due to lack of money. After enlisting in the Army and later failing as an officer's cadet at West Point, Poe parted ways with the Allans. His publishing career began humbly, with an anonymous collection of poems, Tamerlane and Other Poems (1827), credited only to "a Bostonian".
