Lily James and Emily Mortimer are teaming up to bring “The Pursuit of Love” to the small screen. The former will star in the latter’s adaptation of Nancy Miford’s 1945 novel for BBC One, Deadline reports.

Written and directed by Mortimer, the three-part series is set between the First and Second World Wars. “The Pursuit of Love” depicts “the travails of the Radlett family, focusing on Linda, the most beautiful and wayward Radlett daughter, played by James, who falls first for a stuffy Tory politician, then an ardent Communist, and finally a French duke named Fabrice, and her cousin Fanny Logan. Consumed by a desire for love and marriage, the two women are on the hunt for the ideal lover. Their friendship will be put to the test as Fanny settles for a steady life and Linda decides to follow her heart, to increasingly wild and outrageous places,” the source hints. “As pre-war political divisions split the nation, these women’s diverging choices raise personal questions that are relevant today – about freedom, love, sexual politics, and the mystery of the human heart.”

“The Pursuit of Love” is the first book in a trilogy. The novel is followed by “Love In A Cold Climate” and “Don’t Tell Alfred.”

The project marks Mortimer’s directorial debut. The actress’ recent on-screen credits include “Mary Poppins Returns” and “The Party.” She previously co-created, wrote for, and starred in HBO and Sky comedy “Doll & Em,” and according to Deadline, she’s “currently penning a reboot of classic British legal drama ‘Rumpole of the Bailey,’ originally created by her father.”

James broke out with her role as Lady Rose MacClare in “Downton Abbey.” “Cinderella,” “Mamma Mia! Here We Go Again,” and “Yesterday” are among her feature credits.
