Rob Osler is an award-winning author known for his cozy and historical mysteries, including his innovative "quozy" genre that blends both styles. He is the USA Today bestselling author of "The Case of the Missing Maid," the first book in the Harriet Morrow Investigates series, which received a starred review from Publishers Weekly and was named a New York Times "Standout Historical Fiction Release." His contemporary comedic series Hayden & Friends Mysteries, beginning with "Devil’s Chew Toy," earned critical acclaim, with its sequel "Cirque du Slay" winning the 2025 Left Coast Crime Award for Best Humorous Novel. Osler's short stories, including the Edgar-finalist "Miss Direction" and Robert L. Fish Award-winning "Analogue," have also garnered significant recognition.
Osler's career spans decades, beginning with advertising copywriting before transitioning into brand strategy. A graduate in philosophy from the University of Puget Sound, he later earned an MBA from the University of Washington’s Foster School. His professional background informs his sharp, character-driven narratives, which often feature queer protagonists and witty, fast-paced plots. Themes of identity, justice, and humor permeate his works, earning him accolades such as finalist nominations for the Edgar, Anthony, Macavity, Agatha, and Lefty Awards.
Born in Boise, Idaho, Osler has lived in Chicago and Seattle—settings that inspire his series—before settling in California with his husband and their cat. A member of Mystery Writers of America, Sisters in Crime, and Queer Crime Writers, he continues to expand his literary contributions with forthcoming works, including the second Harriet Morrow novel, "The Case of the Murdered Muckraker," set for release in 2026.
