Isabelle Holland was a prolific Swiss-American author who wrote over 50 books across multiple genres, including Gothic novels, adult mysteries, romantic thrillers, and children's literature.

Born in Basel, Switzerland in 1920, Holland spent her early years in Liverpool where her father served as the American Consul during World War II. She relocated to America in 1940 due to the war, eventually establishing herself as a versatile writer capable of crafting compelling narratives for both young adult and adult audiences. Her works often blended suspense with psychological depth, particularly in her Gothic fiction and mystery novels. Holland's career demonstrated remarkable longevity, continuing to produce new material throughout her life while maintaining residences in both New York City and Switzerland.
