Canadian author Andrew Pyper, known for his acclaimed thrillers such as Lost Girls and The Demonologist, has passed away at the age of 56. PEOPLE confirms that the bestselling novelist died on Friday, Jan. 3, due to complications from cancer. According to his obituary, Pyper spent his final moments peacefully at home, surrounded by his wife of over 20 years, Heidi, and their children, Maude and Ford.

Andrew Pyper (1967–2025) was a celebrated Canadian author renowned for his gripping thrillers and horror novels that combined literary elegance with spine-chilling storytelling. Born in Stratford, Ontario, Pyper displayed an early interest in literature, which led him to pursue an English degree at McGill University and later a law degree from the University of Toronto. Despite earning his law degree, Pyper never practiced law, choosing instead to dedicate his life to writing.

His debut novel, Lost Girls (1999), launched his literary career to critical acclaim. A dark and atmospheric tale set in small-town Canada, the book earned the Arthur Ellis Award for Best First Novel and established Pyper as a master of psychological suspense. The success of Lost Girls was followed by a string of bestselling works, including The Trade Mission (2002), The Killing Circle (2008), and The Demonologist (2013), which won the International Thriller Writers Award for Best Hardcover Novel.

Pyper’s stories often explored themes of human frailty, the supernatural, and the darkness lurking within seemingly ordinary lives. His writing was distinguished by its vivid imagery, complex characters, and a unique ability to blend the fantastical with the real. This skill made his novels resonate deeply with readers and critics alike.
