Wilkie Collins (1824-1889) was an English novelist and playwright. Born in London, Collins was raised in England, Italy, and France by William Collins, a renowned landscape painter, and his wife Harriet Geddes. After working for a short time as a tea merchant, he published Antonina (1850), his literary debut. He quickly became known as a leading author of sensation novels, a popular genre now recognized as a forerunner to detective fiction. Encouraged on by the success of his early work, Collins made a name for himself on the London literary scene. He soon befriended Charles Dickens, forming a strong bond grounded in friendship and mentorship that would last several decades. His novels The Woman in White (1859) and The Moonstone (1868) are considered pioneering examples of mystery and detective fiction, and enabled Collins to become financially secure. Toward the end of the 1860s, at the height of his career, Collins began to suffer from numerous illnesses, including gout and opium addiction, which contributed to his decline as a writer. Beyond his literary work, Collins is seen as an early advocate for marriage reform, criticizing the institution and living a radically open romantic lifestyle.

Walter Besant (1836-1901) was born in Portsmouth, Hampshire and studied at King's College, London. He would later work in higher education at Royal College, Mauritius, where he taught mathematics. During this time, Besant also began his extensive writing career. In 1868 he published Studies in Early French Poetry followed by a fruitful collaboration with James Rice, which produced Ready-money Mortiboy (1872), and The Golden Butterfly(1876). Besant's career spanned genres and mediums including fiction, non-fiction, plays and various collections.
