"Little Pipes" (also known as "Pijpelijntjes" in Dutch) is a novel written by Jacob Israël de Haan, a Dutch poet and writer. The novel explores the themes of homosexuality, identity, and societal taboos. It tells the story of two young men, Sam and Joop, who are in love but struggle to find acceptance and happiness in a society that discriminates against same-sex relationships. Set in the early 20th century, the novel offers a poignant and realistic portrayal of the challenges faced by LGBT individuals during that time. "Little Pipes" was published in 1904 under a pseudonym due to the controversial nature of its subject matter.
