She also wrote under the pen names Peter Curtis and Juliet Astley. Lofts chose to release her murder-mystery novels under the pen name Peter Curtis because she did not want the readers of her historic fiction to pick up a murder-mystery novel and expect classic Lofts historical fiction. However, the murders still show characteristic Lofts elements. Most of her historical novels fall into two general categories: biographical novels about queens, among them Anne Boleyn, Isabella I of Castile, and Catherine of Aragon; and novels set in East Anglia centered around the fictitious town of Baildon (patterned largely on Bury St. Edmunds). Her creation of this fictitious area of England is reminiscent of Thomas Hardy's creation of "Wessex"; and her use of recurring characters such that the protagonist of one novel appears as a secondary character in others is even more reminiscent of William Faulkner's work set in "Yoknapatawpha County," Mississippi. Lofts' work set in East Anglia in the 1930s and 1940s shows great concern with the very poor in society and their inability to change their conditions. Her approach suggests an interest in the social reformism that became a feature of British post-war society.
