Gail Lynn Frazer, a mystery author who wrote under the pseudonym Margaret Frazer, has passed away. She was 66 years old. Her son, Justin Alexander, revealed the sad news on her website.

Throughout her career, Frazer (pictured) wrote more than twenty books. The award-winning writer was nominated twice for the prestigious Edgar Award. A funeral has been planned for February 8th.

Here’s more from the announcement: “Twenty years ago, Frazer’s first novel – The Novice’s Tale – was published the same summer that she was first diagnosed with breast cancer. She published her twenty-fifth novel – The Circle of Witches – last December at a time when she was struggling with the fifth recurrence of the cancer. She fought long, she fought stubbornly, and she refused to be defined by the disease which ultimately claimed her life. In her work, she sought the unique pleasure of thoroughly exploring the otherwhen and otherwhere.” (via Mystery Fanfare)
