Her circle of celebrity friends also included T. S. Eliot; Gertrude Stein, who mentions Mirrlees in Everybody's Autobiography; Bertrand Russell; and Ottoline Morrell.

[6][7] Mirrlees set her first novel, Madeleine: One of Love's Jansenists (1919), in and around the literary circles of the 17th Century Précieuses, and particularly those salons frequented by Mlle de Scudéry.

Lud-in-the-Mist was reprinted in 1970 in mass-market paperback format by Lin Carter, without the author's permission, for the Ballantine Adult Fantasy series, and then again by Del Rey in 1977.

The "unauthorised" nature of the 1970 reprint is explained by the fact that, as Carter indicated in his introduction, he and the publishing company could not even ascertain whether the author was alive or dead, "since our efforts to trace this lady [Mirrlees] have so far been unsuccessful."

Since 2000, Mirrlees' work has undergone another resurgence in popularity, marked by new editions of her poetry, an entry in the Dictionary of National Biography and several scholarly essays by critic Julia Briggs, new introductions to Lud-in-the-Mist by writer Neil Gaiman and scholar Douglas A. Anderson, essays and a brief biography by writer Michael Swanwick, an artist-book facsimile reprint of Paris, a poem by printer and publisher Hurst Street Press, and translations of Lud-in-the-Mist into German and Spanish.
