The Knickerbocker Gang is a series of books for children by Austrian writer Thomas Brezina.
 It features stories about junior detectives called Axel, Poppi, Lilo and Dominik, who solve mysteries.
 The books have been translated to many different languages.
 They remain a huge favorite in Turkey in the children's novels sections, even finding a place on many primary school curricula.
 A 1997 Austrian TV series was based on the books.
The Hardy Boys, Frank and Joe Hardy, are fictional characters who appear in various mystery series for children and teens.
Clinton Walker (born 1957) is an Australian writer, best known for his works on popular music but with a broader interest in social and cultural history and theory.
 Sydney's "Sun-Herald" has called him "our best chronicler of Australian grass-roots culture."
 He has always been ahead of the curve.
 As "Rhythms" magazine said in 2015, "Like many of Walker’s projects, "Buried Country" was at least a decade ahead of its time," and as such he is remarkable as a critic who has exerted a pro-active impact on Australian music and its development; groundbreaking books like "Inner City Sound" (1981) and "Buried Country" (2000) especially have informed and inspired successive generations of musicians.
 Similarly, while he found best-selling success as Bon Scott's biographer, Walker's non-music books like "Football Life" (1998) and "Golden Miles" (2005) have innovatively offered an appreciation of subjects hitherto hardly deemed worthy of serious consideration.
The Mysteries of Alfred Hedgehog, also known as Les Mystères d'Alfred, is an animated French and Canadian animated series that airs on several broadcast and cable networks around the world.
 The characters of the show consist of mainly the anthropomorphic woodland animals such as raccoons, moose and voles.
 The show follows three anthropomorphic animal pre-teens — Alfred Hedgehog, Milo Skunk and Camille Wallaby—as they solve mysteries in Gnarly Woods.
Busytown Mysteries, also known as Hurray for Huckle!
, is a Canadian animated television series created by Cookie Jar Entertainment.
 Currently the series airs in Canada as part of the Kids' CBC block on the Tiny Pop channel and in the United States as part of the Cookie Jar TV block on CBS.
 It's also on ITunes and there's no report yet about things like a Blu-ray, Amazon, or Hulu release.
 It takes place in Richard Scarry's Busytown and teaches the scientific method through stories in which Huckle Cat (with his sister Sally Cat, and friend Lowly the Worm) solve mysteries by examining evidence.
The Sting of the Scorpion is Volume 58 in the original The Hardy Boys Mystery Stories published by Grosset & Dunlap.
The Happy Hollisters is a series of books about a family who loves to solve mysteries.
 The series was published by the Stratemeyer Syndicate and entirely written by Andrew E. Svenson (1910–1975) under the pseudonym Jerry West.
 Helen S. Hamilton (1921–2014) illustrated the books.
The Mandie books are a children's historical mystery series written by Lois Gladys Leppard, intended for children aged 8 to 12.
 Since the publication of the first book in 1983, more than seven million copies have been printed of the Mandie series.
 There are forty novels in the main series and eight in the junior series, along with several special books.
 The setting of the series is mostly in North Carolina in the early 20th century, although Mandie and her friends travel to Charleston, Washington D.C., Europe and New York City throughout the series to solve mysteries.
 The story starts around the year 1900, when Mandie is 11 years old.
 In every book she finds a mystery to solve with her good friends Joe Woodard and Celia Hamilton.
Kate Fansler is the main character in a series of fourteen mystery novels written by Carolyn Gold Heilbrun from 1964-2002, under the pseudonym Amanda Cross.
 Like Heilbrun, Fansler was a literature professor at a prestigious New York university.
 In the books, she is called upon to solve mysteries set in an academic context, usually involving the murder of a professor or student.
 Her work is accomplished through conversation with the people involved, rather than through the physically adventurous antics preferred by other fictional detectives.
 Midway through the series, she married her partner, district attorney Reed Amhearst, but as she tells another character in "A Trap For Fools", she "neither uses his name nor wears his ring".
 Echoing Heilbrun's personal views, she has little sentimental attachment to children, enjoys smoking, drinking, and fatty food, and in later books such as "Sweet Death, Kind Death", meditates on the nature of middle age and on the liberating nature of death.
Lynn Haney is an American biographer.
 Haney recounted the lives of people such as Josephine Baker and Gregory Peck.
 Haney is recognized for her balance of thorough research and respect for the subjects of her books, as demonstrated in both "Naked At the Feast" and "A Charmed Life".
 She wrote eleven books including "I Am A Dancer," and "The Lady Is A Jock" as well as children's books like "Perfect Balance: The Story of an Elite Gymnast" and Skaters, Profile of a Pair.
 Before writing full-time, Haney worked for the "New York Times" and "CBS News".
 Haney lives in Guilford, Connecticut.
