The pen name was originally shared by Frazer and Mary Monica Pulver Kuhfeld in their collaboration on The Novice's Tale, the first of the Sister Frevisse books featuring the Benedictine nun Dame Frevisse. Their collaboration came to an end with The Murderer's Tale, the sixth book in the series. Starting with the Edgar Award-nominated The Prioress' Tale, the Margaret Frazer pen name was used exclusively by Gail Brown. She also wrote the Player Joliffe mysteries, starring the medieval actor Joliffe.
